Gearbox shell machining process design《Manufacturing Engineering and Technology—Machining》Mechanical Industry Press In March 2004, version 1 p560—564（Serope kalpakjian）（Steven R.Schmid）AbstractGearbox shell is a more complex structure of spare parts box, its high precision, complex process, and the processing quality will affect the overall performance engine, so it has become the engine manufacturer's focus parts one.Machining process planning must guarantee the machining quality of parts, to meet the technical requirements stipulated in drawings, at the same time should also have high productivity and efficiency. Therefore, machining process planning design is an important work, requires designers must have a rich experience in production practice and wide range of mechanical manufacturing technology basic theory knowledge. In the specified procedure, should according to the production of parts and the existing equipment conditions, taking the processing quality into account, productivity and economy requirements, after repeated analysis and comparison, to determine the optimal or the best solution.1.Technical Characteristics of the gearbox shellThe gearbox shell process features are: the structure of complex shape; processing plane, more than holes; uneven wall thickness and stiffness is low; processing of high precision typical of box-type processing part. The main processing of the surface of cylinder block top surface, the main bearing side, cylinder bore, the main and camshaft bearing bore holes and so on, they will directly affect the machining accuracy of the engine assembly precision and performance, mainly rely on precision equipment, industrial fixtures reliability and processing technology to ensure the reasonableness.2.The gearbox shell process design principles and the basisDesign Technology program should be to ensure product quality at the same time, give full consideration to the production cycle, cost and environmental protection; based on the enterprises ability to actively adopt advanced process technology and equipment, and constantly enhance their level of technology. Gearbox shell machining process design should follow the following basic principles: 2.1 The selection of processing equipmentThe principle of selection adopted the principle of selection adopted the principle of combining rigid-flexible, processing each horizontal machining center is located mainly small operations with vertical machining center, the key process a crank hole, cylinder hole, balancer shaft hole High-speed processing of high-precision horizontal machining center, an upper and lower non-critical processes before and after the four-dimensional high-efficiency rough milling and have a certain adjustment range of special machine processing;2.2 Concentration process principleFocus on a key process in principle process the body cylinder bore, crankshaft hole, Balance Shaft hole surface finishing and the combination of precision millingcylinder head, using a process focused on a setup program to complete all processing elements in order to ensure product accuracy The key quality processes to meet the cylinder capacity and the relevant technical requirements;3.The gearbox shell machining process design the main contentGearbox shell complex structure, high precision, arge size, is thin-walled parts, there are a number of high precision plane and holes. Engine block machining process characteristics; mainly flat and the hole processing, processing of flat generally use planing, milling methods such as processing, processing of hole used mainly boring, processing and multi-purpose drilling holes. As the cylinder complex structure. so how to ensure that the mutual position of the surface processing precision is an important issue.3.1 The selection of blankGearbox shell on the materials used are generally gray cast iron HT150,HT200,HT250,there is also cast aluminum or steel plate, this engine block using high-strength alloy cast iron. Cylinder in the processing prior to aging treatment in order to eliminate stress and improve the rough casting mechanical properties. Improve the rough accuracy, reduction of machining allowance, is to improve the automated production line system productivity and processing quality of the important measures. As the foreign box-type parts of rough quality and high precision, and its production-line system has been implemented directly on the blank line, not only eliminating the need for blank check device also saves the rough quality problems due to waste of machining time, increase overall efficiency. Therefore, the refinement of rough is to improve the productivity of the most promising way out. For the engine block production line, can be rough in parts on-line pre-milling six face, removing most of the margin, to facilitate direct on-line parts.3.2 Machining process selection and processing of the benchmarkChoose the right processing technology base is directly related to the processing quality can ensure the parts. Generally speaking, process benchmarking can be divided into coarse and fine reference base.3.2.1 Coarse reference baseThe baseline for the on-line thick rough ,which is particularly important the choice of benchmark crude, if crude benchmark choice unreasonable, will the uneven distribution of machining allowance, processing and surface offsets, resulting in waste. In the cylinder production line, we have adopted for the coarse side of the base;3.2.2 Fine reference baseRefined the base of this box for the engine block parts, the general use of "side two sales "for a full range of uniform benchmarks, For the longer automated production positioning. In the gearbox shell of the process, we have adopted to the side, bottom and the spindle hole positioning, in the processing center on the process.3.3 Machining Processing Stages and processes of the arrangementsOften a part of many apparent need for processing, of course, the surface machining accuracy are different. Processing of high precision surface, often afterrepeated processing; As for the processing of the surface of low precision, only need to go through one or two on the list. Thus, when the development process in order to seize the "processing high precision surface, "this conflict, the reasonable arrangement processes and rational division stage of processing. Arrange the order of the principle of process is: after the first coarse refined, the first surface after the hole, the first benchmark other. In the engine block machining, the same should follow this principle.3.3.1 roughing stage engine block machining processThe arrangements for roughing process, to fully carry out rough rough, trim most of the margin in order to ensure production efficiency;3.3.2 semi-finishing phase of the engine block machiningIn order to ensure the accuracy of the middle of some important surface processing, and arrange some semi-finishing operations, will be required accuracy and surface roughness of the surface of the middle of some processing to complete, while demanding the surface of semi-finished, to prepare for future finishing;3.3.3 The finishing stageThe finishing stage of requiring high accuracy and surface roughness of the surface processing; 3.3.4 secondary processingSecondary processing such as small surface screw holes, you can finish of the major surface after the one hand, when the workpiece deformation process little impact at the same time also reduced the rejection rate;In addition,if the main surface of a waste,these small the surface will not have to be processed,thus avoiding a waste of man-hours.However,if the processing is very easy for a small surface bumps the main surface,it should be placed on a small surface finish prior to the main surface finishing;3.3.5 make proper arrangements for secondary processesMake proper arrangements for secondary processes such as product inspection process,in part roughing stage,the key process before and after processing,spare parts all the processing has been completed,should be appropriate arrangements. Stage of processing division,has the following advantages:First,it can take measures to eliminate the rough workpiece after the stress,to ensure accuracy; second,finishing on the back,and will not damage during transport the surface of the workpiece has been processed;again,first roughing the surface defects can be detected early and promptly deal with rough,do not waste working hours.But most small parts,do not sub very thin.3.4 The gearbox shell surface of the main processing and secondary processes3.4.1 Plane processingPlane processing at present, the milling of engine blocks is the primary means of planar processing,domestic milling feed rate is generally 300-400mm/min,and foreign 2000-4000mm/min milling feed rate compared to far cry,to be on increasing,therefore,improve the milling feed rate,reduce overhead time is to improve the productivity of the major means of finishing a number of plane engine block when the milling feed rate to reach 2399mm/min,greatly improved efficiency; Top surface of the cylinder milling is a key process in the process,the flatnessrequirements for 0.02/145mm,the surface roughness of Ra1.6um.Processing in the cylinder,the use of side and spindle bearing bore positioning,top,bottom and middle vagay only aperture while processing used in the processing line outside of the knife device can better meet the engine block machining accuracy;3.4.2 General holes MachiningGeneral holes Machining holes in general are still using the traditional processing of drilling,expansion,boring,reaming,tapping and other craft approach. Issues in the design process of specific programs,use of coated cutting tools,cutting tools and other advanced tools within the cooling,and using a large flow of cooling systems,greatly improving the cutting speed,improved productivity;3.4.3 Deep hole processingDeep hole processing of the traditional processing method is used to grade twist drill feed,low efficiency of their production,processing and quality is poor.The deep hole in the engine block processing,the use of gun drilling process;3.4.4 CleaningCleaning is divided into wet cleaning and dry cleaning.Machining cylinder automatic production line using a large flow of wet cleaning;3.4.5 DetectionDetect points outside the line detection and line detection of two kinds. Quality inspection in the engine block,according to the actual situation with lines outside the detection,the main use of coordinate measuring machine integrated measurements of the cylinder,each 200 samples 1-5 pieces,each class random one.变速箱壳体机械加工工艺设计摘自：《机械工程与技术（机加工）》（英文版）机械工业出版社2004年3月第1版美国卡卡尔帕基安·施密德摘要变速箱壳体是变速器机零件中结构较为复杂的箱体零件，其精度要求高，加工工艺复杂，并且加工加工质量的好坏直接影响发动机整个机构的性能，因此，它成为各个发动机生产厂家所关注的重点零件之一。

附录A 英文文献Final drive\DifferentialAll vehicles have some type of drive axle/differential assembly incorporated into the driveline. Whether it is front, rear or four wheel drive, differentials are necessary for the smooth application of engine power to the road.PowerflowThe drive axle must transmit power through a 90° angle. The flow of power in conventional front engine/rear wheel drive vehicles moves from the engine to the drive axle in approximately a straight line. However, at the drive axle, the power must be turned at right angles (from the line of the driveshaft) and directed to the drive wheels.This is accomplished by a pinion drive gear,which turns a circular ring gear. The ring gear is attached to a differential housing, containing a set of smaller gears that are splined to the inner end of each axle shaft. As the housing is rotated, the internal differential gears turn the axle shafts, which are also attached to the drive wheels.Fig 1 Drive axleRear-wheel driveRear-wheel-drive vehicles are mostly trucks, very large sedans and many sports car and coupe models. The typical rear wheel drive vehicle uses a front mounted engine and transmission assemblies with a driveshaft coupling the transmission to the rear drive axle. Drive in through the layout of the bridge, the bridge drive shaft arranged vertically in the same vertical plane, and not the drive axle shaft, respectively, in their own sub-actuator with a direct connection, but the actuator is located at the front or the back of the adjacent shaftof the two bridges is arranged in series. Vehicle before and after the two ends of the driving force of the drive axle, is the sub-actuator and the transmission through the middle of the bridge. The advantage is not onlya reduction of the number of drive shaft, and raise the driving axle of the common parts of each other, and to simplify the structure, reduces the volume and quality.Fig 2 Rear-wheel-drive axle Some vehicles do not follow this typical example. Such as the older Porsche or Volkswagen vehicles which were rear engine, rear drive. These vehicles use a rear mounted transaxle with halfshafts connected to the drive wheels. Also, some vehicles were produced with a front engine, rear transaxle setup with a driveshaft connecting the engine to the transaxle, and halfshafts linking the transaxle to the drive wheels.Differential operationIn order to remove the wheel around in the kinematics due to the lack of co-ordination about the wheel diameter arising from a differentor the same rolling radius of wheel travel required, inter-wheel motor vehicles are equipped with about differential, the latter to ensure that the car driver Bridge on both sides of the wheel when in range with a trip to the characteristics of rotating at different speeds to meet the requirements of the vehicle kinematics.Fig 3 Principle of differentialThe accompanying illustration has been provided to help understand how this occurs.1.The drive pinion, which is turned by the driveshaft, turns the ring gear.2.The ring gear, which is attached to the differential case, turns the case.3.The pinion shaft, located in a bore in the differential case, is at right angles to the axle shafts and turns with the case.4.The differential pinion (drive) gears are mounted on the pinion shaft and rotate with the shaft .5.Differential side gears (driven gears) are meshed with the pinion gears and turn with the differential housing and ring gear as a unit.6.The side gears are splined to the inner ends of the axle shafts and rotate the shafts as the housing turns.7.When both wheels have equal traction, the pinion gears do not rotate on the pinion shaft, since the input force of the pinion gears is divided equally between the two side gears.8.When it is necessary to turn a corner, the differential gearing becomes effective and allows the axle shafts to rotate at different speeds .Open-wheel differential on each general use the same amount of torque. To determine the size of the wheel torque to bear two factors: equipment and friction. In dry conditions, when a lot of friction, the wheel bearing torque by engine size and gear restrictions are hours in the friction (such as driving on ice), is restricted to a maximum torque, so that vehicles will not spin round. So even if the car can produce more torque, but also need to have sufficient traction to transfer torque to the ground. If you increase the throttle after the wheels slip, it will only make the wheels spin faster.Fig 4 Conventional differential Limited-slip and locking differential operationFig 5 Limited-slip differentialDifferential settlement of a car in the uneven road surface and steering wheel-driven speed at about the different requirements; but is followed by the existence of differential in the side car wheel skid can not be effective when the power transmission, that is, the wheel slip can not produce the driving force, rather than spin the wheel and does not have enough torque. Good non-slip differential settlement of the car wheels skid on the side of the power transmission when the issue, that is, locking differential, so that no longer serve a useful differential right andleft sides of the wheel can be the same torque.Limited-slip and locking differential operation can be divided into two major categories：(1) mandatory locking type in ordinary differential locking enforcement agencies to increase, when the side of the wheel skid occurs, the driver can be electric, pneumatic or mechanical means to manipulate the locking body meshing sets of DIP Shell will be with the axle differential lock into one, thus the temporary loss of differential role. Relatively simple structure in this way, but it must be operated by the driver, and good roads to stop locking and restore the role of differential.(2) self-locking differential installed in the oil viscosity or friction clutch coupling, when the side of the wheel skid occurs when both sides of the axle speed difference there, coupling or clutch friction resistance on the automatic, to make certain the other side of the wheel drive torque and the car continued to travel. When there is no speed difference on both sides of the wheel, the frictional resistance disappeared, the role of automatic restoration of differentials. More complicated structure in this way, but do not require drivers to operate. Has been increasingly applied in the car. About non-slip differential, not only used for the differential between the wheels, but also for all-wheel drive vehicle inter-axle differential/.Gear ratioThe drive axle of a vehicle is said to have a certain axle ratio. This number (usually a whole number and a decimal fraction) is actually a comparison of the number of gear teeth on the ring gear and the pinion gear. For example, a 4.11 rear means that theoretically, there are 4.11 teeth on the ring gear for each tooth on the pinion gear or, put anotherway, the driveshaft must turn 4.11 times to turn the wheels once. The role of the final drive is to reduce the speed from the drive shaft, thereby increasing the torque. Lord of the reduction ratio reducer, a driving force for car performance and fuel economy have a greater impact. In general, the more reduction ratio the greater the acceleration and climbing ability, and relatively poor fuel economy. However, if it is too large, it can not play the full power of the engine to achieve the proper speed. The main reduction ratio is more Smaller ，the speed is higher, fuel economy is better, but the acceleration and climbing ability will be poor.附录B 文献翻译主减速器和差速器所有的汽车都装有不同类型的主减速器和差速器来驱动汽车行驶。

Unit 1 Metals金属Unit 2 Selection of Construction Materials工程材料的选择Unit 3 Mechanical Properties of MaterialsUnit5 Design of machine and machine elements机器和机器零件的设计Machine design机器设计1 Machine design is the art of planning or devising new or improved machines to accomplish specific purposes. In general, a machine will consist of a combination of several different mechanical elements properly designed and arranged to work together, as a whole. During theinitial planning of a machine, fundamental decisions must be made concerning loading, type of kinematic elements to be used, and correct utilization of the properties of engineering materials. Economic considerations are usually of prime importance when the design of new machinery is undertaken. In general, the lowest over-all costs are designed. Consideration should be given not only to the cost of design, manufacture the necessary safety features and be of pleasing external appearance. The objective is to produce a machine which is not only sufficiently rugged to function properly for a reasonable life, but is at the same time cheap enough to be economically feasible.机器设计为了特定的目的而发明或改进机器的一种艺术。

2、应力和应变在任何工程结构中独立的部件或构件将承受来自于部件的使用状况或工作的外部环境的外力作用。
如果组件就处于平衡状态,由此而来的各种外力将会为零,但尽管如此,它们共同作用部件的载荷易于使部件变形同时在材料里面产生相应的内力。
有很多不同负载可以应用于构件的方式。
负荷根据相应时间的不同可分为:(a)静态负荷是一种在相对较短的时间内逐步达到平衡的应用载荷。
(b)持续负载是一种在很长一段时间为一个常数的载荷, 例如结构的重量。
这种类型的载荷以相同的方式作为一个静态负荷; 然而,对一些材料与温度和压力的条件下,短时间的载荷和长时间的载荷抵抗失效的能力可能是不同的。
(c)冲击载荷是一种快速载荷(一种能量载荷)。
振动通常导致一个冲击载荷, 一般平衡是不能建立的直到通过自然的阻尼力的作用使振动停止的时候。
(d)重复载荷是一种被应用和去除千万次的载荷。
(e)疲劳载荷或交变载荷是一种大小和设计随时间不断变化的载荷。
上面已经提到，作用于物体的外力与在材料里面产生的相应内力平衡。
因此,如果一个杆受到一个均匀的拉伸和压缩，也就是说, 一个力,均匀分布于一截面,那么产生的内力也均匀分布并且可以说杆是受到一个均匀的正常应力,应力被定义为应力==负载 P /压力 A,因此根据载荷的性质应力是可以压缩或拉伸的,并被度量为牛顿每平方米或它的倍数。
如果一个杆受到轴向载荷，即是应力，那么杆的长度会改变。
如果杆的初始长度L和改变量△L已知，产生的应力定义如下:应力==改变长△L /初始长 L因此应力是一个测量材料变形和无量纲的物理量 ,即它没有单位;它只是两个相同单位的物理量的比值。
一般来说,在实践中,在荷载作用下材料的延伸是非常小的, 测量的应力以*10-6的形式是方便的, 即微应变, 使用的符号也相应成为ue。
从某种意义上说，拉伸应力与应变被认为是正的。
压缩应力与应变被认为是负的。
因此负应力使长度减小。
当负载移除时，如果材料回复到初始的，无负载时的尺寸时，我们就说它是具有弹性的。

毕业设计论文外文资料原文及译文学院：机电工程学院专业：机械设计制造及其自动化班级：学号：姓名：Mechanical engineering1.The porfile of mechanical engineeringEngingeering is a branch of mechanical engineerig,it studies mechanical and power generation especially power and movement.2.The history of mechanical engineering18th century later periods,the steam engine invention has provided a main power fountainhead for the industrial revolution,enormously impelled each kind of mechznical biting.Thus,an important branch of a new Engineering – separated from the civil engineering tools and machines on the branch-developed together with Birmingham and the establishment of the Associantion of Mechanical Engineers in 1847 had been officially recognized.The mechanical engineering already mainly used in by trial and error method mechanic application technological development into professional engineer the scientific method of which in the research,the design and the realm of production used .From the most broad perspective,the demend continuously to enhance the efficiencey of mechanical engineers improve the quality ofwork,and asked him to accept the history of the high degree of education and training.Machine operation to stress not only economic but also infrastructure costs to an absolute minimun.3.The field of mechanical engineeringThe commodity machinery development in the develop country,in the high level material life very great degree is decided each kind of which can realize in the mechanical engineering.Mechanical engineers unceasingly will invent the machine next life to produce the commodity,unceasingly will develop the accuracy and the complexity more and more high machine tools produces the machine.The main clues of the mechanical development is:In order to enhance the excellent in quality and reasonable in price produce to increase the precision as well as to reduce the production cost.This three requirements promoted the complex control system development.The most successful machine manufacture is its machine and the control system close fusion,whether such control system is essentially mechanical or electronic.The modernized car engin production transmission line(conveyer belt)is a series of complex productions craft mechanizationvery good example.The people are in the process of development in order to enable further automation of the production machinery ,the use of a computer to store and handle large volumes of data,the data is a multifunctional machine tools necessary for the production of spare parts.One of the objectives is to fully automated production workshop,three rotation,but only one officer per day to operate.The development of production for mechanical machinery must have adequate power supply.Steam engine first provided the heat to generate power using practical methods in the old human,wind and hydropower,an increase of engin .New mechanical engineering industry is one of the challenges faced by the initial increase thermal effciency and power,which is as big steam turbine and the development of joint steam boilers basically achieved.20th century,turbine generators to provide impetus has been sustained and rapid growth,while thermal efficiency is steady growth,and large power plants per kW capital consumption is also declining.Finally,mechanical engineers have nuclear energy.This requires the application of nuclear energy particularly high reliability and security,which requires solving many new rge power plants and the nuclear power plant control systems have become highly complex electroonics,fluid,electricity,water and mechanical parts networks All in all areas related to the mechanical engineers.Small internal combustion engine,both to the type (petrol and diesel machines)or rotary-type(gas turbines and Mong Kerr machine),as well as their broad application in the field of transport should also due to mechanical enginerrs.Throughout the transport,both in the air and space,or in the terrestrial and marine,mechanial engineers created a variety of equipment and power devices to their increasing cooperation with electrical engineers,especially in the development of appropration control systems.Mechanical engineers in the development of military weapons technology and civil war ,needs a similar,though its purpose is to enhance rather than destroy their productivity.However.War needs a lot of resources to make the area of techonlogy,many have a far-reaching development in peacetime efficiency.Jet aircraft and nuclear reactors are well known examples.The Biological engineering,mechanical engineering biotechnology is a relatively new and different areas,it provides for the replacement of the machine or increase thebody functions as well as for medical equipment.Artficial limbs have been developed and have such a strong movement and touch response function of the human body.In the development of artificial organ transplant is rapid,complex cardiac machines and similar equipment to enable increasingly complex surgery,and injuries and ill patients life functions can be sustained.Some enviromental control mechanical engineers through the initial efforts to drainage or irrigation pumping to the land and to mine and ventilation to control the human environment.Modern refrigeration and air-conditioning plant commonaly used reverse heat engine,where the heat from the engine from cold places to more external heat.Many mechanical engineering products,as well as other leading technology development city have side effects on the environment,producing noise,water and air pollution caused,destroyed land and landscape.Improve productivity and diver too fast in the commodity,that the renewable naturalforces keep pace.For mechanical engineers and others,environmental control is rapidly developing area,which includes a possible development and production of small quantities of pollutants machine sequnce,and the development of new equipment and teachnology has been to reduce and eliminate pollution.4.The role of mechanical engineeringThere are four generic mechanical engineers in common to the above all domains function.The 1st function is the understanding and the research mechanical science foundation.It includes the power and movement of the relationship dynamics For example,in the vibration and movement of the relationship;Automatic control;Study of the various forms of heart,energy,power relations between the thermodynamic;Fluidflows; Heat transfer; Lubricant;And material properties.The 2nd function will be conducts the research,the desing and the development,this function in turn attempts to carry on the essential change to satisfy current and the future needs.This not only calls for a clear understanding of mechanical science,and have to breakdown into basic elements of a complex system capacity.But also the need for synthetic and innovative inventions.The 3rd function is produces the product and the power,include plan,operation and maintenance.Its goal lies in the maintenance eitherenhances the enterprise or the organization longer-tern and survivabilaty prestige at the same time,produces the greatest value by the least investments and the consumption.The 4th function is mechanical engineer’s coordinated function,including the management,the consultation,as well as carries on the market marking in certain situation.In all these function,one kind unceasingly to use the science for a long time the method,but is not traditional or the intuition method tendency,this is a mechanical engineering skill aspect which unceasingly grows.These new rationalization means typical names include:The operations research,the engineering economics,the logical law problem analysis(is called PABLA) However,creativity is not rationalization.As in other areas,in mechanical engineering,to take unexpected and important way to bring about a new capacity,still has a personal,marked characteristice.5.The design of mechanical engineeringThe design of mechanical is the design has the mechanical property the thing or the system,such as:the instrument and the measuring appliance in very many situations,the machine design must use the knowledge of discipline the and so on mathematics,materials science and mechanics.Mechanical engineering desgin includeing all mechanical desgin,but it was a study,because it also includes all the branches of mechsnical engineering,such as thermodynamics all hydrodynamics in the basic disciplines needed,in the mechanical engineering design of the initial stude or mechanical design.Design stages.The entire desgin process from start to finish,in the process,a demand that is designed for it and decided to do the start.After a lot of repetition,the final meet this demand by the end of the design procees and the plan.Design considerations.Sometimes in a system is to decide which parts needs intensity parts of geometric shapesand size an important factor in this context that we must consider that the intensity is an important factor in the design.When we use expression design considerations,we design parts that may affect the entire system design features.In the circumstances specified in the design,usually for a series of such functions must be taken into account.Howeever,to correct purposes,we should recognize that,in many cases thedesign of important design considerations are not calculated or test can determine the components or systems.Especially students,wheen in need to make important decisions in the design and conduct of any operation that can not be the case,they are often confused.These are not special,they occur every day,imagine,for example,a medical laboratory in the mechanical design,from marketing perspective,people have high expectations from the strength and relevance of impression.Thick,and heavy parts installed together:to produce a solid impression machines.And sometimes machinery and spare parts from the design style is the point and not the other point of view.Our purpose is to make those you do not be misled to believe that every design decision will needreasonable mathematical methods.Manufacturing refers to the raw meterials into finished products in the enterprise.Create three distinct phases.They are:input,processing exprot.The first phase includes the production of all products in line with market needs essential.First there must be the demand for the product,the necessary materials,while also needs such as energy,time,human knowledge and technology resourcess .Finall,the need for funds to obtain all the other resources.

This led to the specialization.Specialization in turn reduce the manufacture of integrated factors.In this stage of development,manufacturing workers can see their production as a whole represent a specific piece of the part of the production process.One can not say that their work is how to cope with the entire production process,or how they were loaded onto a production of parts finished.Development of manufacting processes is the next phase of the selection process automation.This is a computer-controlled machinery and processes.At this stage,automation island began to emerge in the workshop lane.Each island represents a clear production process or a group of processes.Although these automated isolated island within the island did raise the productivity of indivdual processes,but the overall productivity are often not change.This is because the island is not caught in other automated production process middle,but not synchronous with them .The ultimate result is the efficient working fast parked through automated processes,but is part of the stagnation in wages down,causing bottlenecks.To better understand this problem,you can imagine the traffic in the peak driving a red light from the red Service Department to the next scene. Occasionally you will find a lot less cars,more than being slow-moving vehicles,but the results can be found by thenext red light Brance.In short you real effect was to accelerate the speed of a red Department obstruction offset.If you and other drivers can change your speed and red light simultaneously.Will advance faster.Then,all cars will be consistent,sommth operation,the final everyone forward faster.In the workshop where the demand for stable synchronization of streamlined production,and promoted integration of manufacturing development.This is a still evolving technology.Fully integrated in the circumstances,is a computer-controllrd machinery and processing.integrated is completed through computer.For example in the preceding paragraph simulation problems,the computer will allow all road vehicles compatible with the change in red.So that everyone can steady traffic.Scientific analysis of movement,timing and mechanics of the disciplines is that it is composed of two pater:statics and dynamics.Statics analyzed static system that is in the system,the time is not taken into account,research and analysis over time and dynamics of the system change.Dynameics from the two componets.Euler in 1775 will be the first time two different branches: Rigid body movement studies can conveniently divided into two parts:geometric and mechanics.The first part is without taking into account the reasons for the downward movement study rigid body from a designated location to another point of the movement,and must use the formula to reflect the actual,the formula would determine the rigid body every point position. Therefore,this study only on the geometry and,more specifically,on the entities from excision.Obviously,the first part of the school and was part of a mechanical separation from the principles of dynamics to study movement,which is more than the two parts together into a lot easier.Dynamics of the two parts are subsequently divided into two separate disciplines,kinematic and dynamics,a study of movement and the movement strength.Therefore,the primary issue is the design of mechanical systems understand its kinematic.Kinematic studies movement,rather than a study of its impact.In a more precise kinematic studies position,displacement,rotation, speed,velocity and acceleration of disciplines,for esample,or planets orbiting research campaing is a paradigm.In the above quotation content should be pay attention that the content of the Euler dynamics into kinematic and rigid body dynamics is based on the assumptionthat they are based on research.In this very important basis to allow for the treatment of two separate disciplines.For soft body,soft body shape and even their own soft objects in the campaign depends on the role of power in their possession.In such cases,should also study the power and movement,and therefore to a large extent the analysis of the increased complexity.Fortunately, despite the real machine parts may be involved are more or less the design of machines,usually with heavy material designed to bend down to the lowest parts.Therefore,when the kinematic analysis of the performance of machines,it is often assumed that bend is negligible,spare parts are hard,but when the load is known,in the end analysis engine,re-engineering parts to confirm this assnmption.机械工程1.机械工程简介机械工程是工程学的一个分支，它研究机械和动力的产，尤其是力和动力。

A NOVEL INTEGRATED SYSTEM FOR RAPID PRODUCT DEVELOPMENTThis paper presents a novel integrated system of rapid product development for reducing the time and cost of product development. The system is composed of four building blocks —digital prototype, virtual prototype, physical prototype and rapid tooling manufacturing system. It can aid effectively in product design, analysis, prototype, mould, and manufacturing process development by integrating closely the various advanced manufacturing technologies which involve the 3D CAD, CAE, reverse engineering, rapid prototyping and rapid tooling. Furthermore, two actual examples are provided to illustrate the application of this integrated system. The results indicate that the system has a high potential to reduce further the cycle and cost of product development.Keywords: Rapid product development; rapid prototyping; integrated system.1. IntroductionDue to the pressure of international competition and market globalization in the 21st century, there continues to be strong driving forces in industry to compete effectively by reducing manufacturing times and costs while assuring high quality products and services. Current industries are facing the new challenges: quick response to business opportunity has been considered as one of the most important factors to ensure company competitiveness; manufacturing industry is evolving toward digitalization, network and globalization. Therefore, new products must be more quickly and cheaply developed, manufactured and introduced to the market. In order to meet the demand of rapid product development, the various new technologies such as reverse engineering (RE), 3D CAD, rapid prototyping (RP), and rapid tooling (RT) have emerged and are regarded as key enabling tools with the ability to shorten the product development and manufacturing time. For example, it has been claimed that RP can cut new product development costs by up to 70% and the time to market by 90%.1 In the form of a better design, more design possibilities, a 3D CAD model can be shown to the customer for approval and prevents misunderstandings. A virtual prototyping is employed to guide in optimizationof the product design and manufacturing process planning, which may result in the accurate determination of the process parameters, and reduce the number of costly physical prototype iterations. Rapid tooling technique offers a fast and low cost method to produce moulds, and shows a high potential for faster response to market demands. When properly integrated among 3D CAD, CAE, RE, RP and RT, these technologies will play a much more important role to reduce further the development cycle and cost of the product production. On the basis of above technologies, a novel integrated system of rapid product development is to be founded so as to meet the requirement of rapid product development.2. Architecture of the Integrated Development SystemThe development process from initial conceptual design to commercial product is an iterative process which includes: product design; analysis of performance, safety and reliability; product prototyping for experimental evaluation; and design modification. Therefore, any step of the new product development process has a direct and strong influence on time-to-market in short order. A good product development system must enable designers or design teams to consider all aspects of product design, manufacturing, selling and recycling at the early stage of the design cycle. So that design iteration and changes can be made easily and effectively. The more fluent the feedback is the higher possibility of success the system has. Design for manufacturing (DFM) and concurrent engineering (CE) necessitate that product and process design be developed simultaneously rather than sequentially.The integrated system of rapid product development is composed of four modules: digital prototype, virtual prototype, physical prototype and rapid tooling.The product development starts from the creation of a 3D CAD model using a CAD software package. At that stage, the product geometry is defined and its aesthetic and dimensional characteristics are verified. The main function of digital prototype is to perform 3D CAD modelling. The CAD model is regarded as a central component of the whole system or project information base which means that in all design, analysis and manufacturing activities the same data is utilized. The product and its components are directly designed on a 3D CAD system (e.g.Pro/Engineer, Unigraphics, CATIA, IDEAS, etc.) during the creative design. If a physical partis ready, the model can be constructed by the reverse engineering technique. RE is a methodology for constructing CAD models of physical parts by digitizing an existing part, creating a digital model and then using it to manufacture components. RE can reduce the development cycle when redesigns become necessary for improved product quality. Preexisting parts with features for improved performance can be readily incorporated into the desired part design. Therefore, it is very useful in creating the CAD model of an existing part when the engineering design is lost or has gone through many design changes. When a designer creates a new design using mock-up, it is also necessary to construct the CAD model of the mock-up for further use of the design data in analysis and manufacturing. The three primary steps in RE process are part digitization, features extraction, and CAD modelling. Part digitization is accomplished by a variety of contact or non-contact digitizers. There are various commercial systems available for part digitization. These systems range from coordinate measuring machine (CMM), laser scanners to ultrasonic digitizers. They can be classified into two broad categories: contact and non-contact. Laser triangulation scanner (LTS), magnetic resonance images (MRI), and computer tomography (CT) are commonly used as non-contact devices. Contact digitizers mainly have CMM and cross-sectional imaging measurement (CIM). Feature extraction is normally achieved by segmenting the digitized data and capturing surface features such as edges. Part modelling is fulfiled through fitting a variety of surfaces to the segmented data points.In order to reduce the iterations of design-prototype-test cycles, increase the product process and manufacturing reliability, it is necessary to guide in optimizing the product design and manufacturing process through virtual prototype (VP). VP is a process of using 3D CAD model, in lieu of a physical prototype, for testing and evaluation of specific characteristics of a product or a manufacturing process. It is often carried out by CAE and virtual manufacturing system. Computer aided engineering (CAE) analysis is an integral part of time-compression technologies. Various software tools available (i.e. ANSYS, MARC, I-DEAS, AUTOFORM, DYNAFORM, etc.) can speed up the development of new products by initiating design optimization before physical prototypes are built. The CAD models can be transferred to a CAE environment for an analysis of the product functional performance and of the manufacturing processes for producing the product’s components. It has also proven to be ofgreat value in the design optimization of part geometry, to determine its dimensions and to control warpage and shrinkage while minimizing process-induced residual stresses and deformations. Virtual manufacturing system (VM) is the natural extension of CAE. It simulates the product functionality and the processes for producing it prior to the development of physical prototypes. VM enables a designer to visualize and optimize a product process with a set of process parameters. The visualization of a virtually simulated part prior to physical fabrication helps to reduce unwanted prototype iterations. Therefore, a product virtual manufacturing system may result in accurate determination of the process parameters, and reduce the number of costly physical prototype iterations. 3D CAD model and VP allow most problems with unfitting to become obvious early in the product development process. Assemblies can be verified for interference as VP can be exercised through a range of tasks. Structure and thermal analysis can be performed on the same model employing CAE applications as well as simulating down-stream manufacturing processes. It is clear that VP increases process and product reliability. Although VP is intended to ensure that unsuitable designs are rejected or modified, in many cases, a visual and physical evaluation of the real component is needed. This often requires physical prototype to be produced. Hence, once the VP is finished, the model may often be sent directly to physical fabrication.The CAD model can be directly converted to the physical prototype using a RP technique or high-speed machining (HSM) process. The 3D CAD model is to be exported not only in the STL format which is considered the de facto standard for interfacing CAD and RP systems, but also in the NC coding which can be used by HSM. HSM has a potential for rapid producing plaster or wooden pattern for RT. RP is a new forming process which fabricates physical parts layer by layer under computer control directly from 3D CAD models in a very short time. In contrast to traditional machining methods, the majority of rapid prototyping systems tend to fabricate parts based on additive manufacturing process, rather than subtraction or removal of material. Therefore, this type of fabrication is unconstrained by the limitations attributed to conventional machining approaches. The application of RP technique as a useful tool can provide benefits throughout the process of developing new products. Specifically, there are serious benefits that RP can bring in the areas of market research, sales support, promotionalmaterial, and the ever-important product launch. Physical RP can also become a powerful communications tool to ensure that everyone involved in the development process fully understands and appreciates the product being developed. Hence, it can help to reduce substantially the inevitable risks in the route from product concept to commercial success, and help shorten time-to-market, improve quality and reduce cost. Over the last 20 years, RP machines have been widely used in industry. The RP methods commercially available include Stereolithgraphy (SLA), Selective Laser Sintering (SLS), Fused Deposition Manufacturing (FDM), Laminated Object Manufacturing (LOM), Ballistic Particle Manufacturing (BMP), and Three-Dimensional Printing (3D printing), etc.Once the design has been accepted, the realization of the production line represents a major task with a long lead time before any product can be put to the market. In particular, the preparation of complex tooling is usually in the critical path of a project and has therefore a direct and strong influence on time-to-market. In order to reduce the product development time and cost, the new technique of RT has been developed. RT is a technique that can transform the RP patterns into functional parts, especially metal parts. It offers a fast and low cost method to produce moulds and functional parts. Furthermore, the integration of both RP and RT in development strategy promotes the implementation of concurrent engineering in companies. Numerous processes have been developed for producing dies from RP system. The RT methods can generally be divided into direct and indirect tooling categories, and also soft (firm) and hard tooling subgroups. Indirect RT requires some kinds of master patterns, which can be made by conventional methods (e.g. HSM), or more commonly by an RP process such as SLA or SLS. Direct RT, as the name suggests, involves the manufacturing of a tool cavity directly on a RP system, hence eliminating the intermediate step of generating a pattern. Soft tooling can be obtained via replication from a positive pattern or master. Soft tooling is associated with low costs; used for low volume production and uses materials that have low hardness levels such as silicones, epoxies, low melting point alloys, etc. RTV silicone rubber moulds, epoxy moulds, metal spraying moulds, etc. are some of these typical soft moldings. Hard tooling is associated with higher volume of production, and the use of materials of greater hardness. Keltool process, Quickcast process, and the ExpressTool process are some of these hard toolings. Electrical discharge machining (EDM) seemsto be an interesting area in which rapid tooling finds a potential application. Some methods of making EDM electrodes based on RP technique have developed, such as abrading process, copper electroforming and net shape casting, etc. On the basis of the above techniques, a novel integrated system of rapid product development is to be proposed. Its overall architecture is shown in Fig. 1.3. Case Studies3.1. Case study 1: ImpellerA total of thirty plastic impellers, with a relatively complex geometry, were required by acustomer within fifteen working days from the receipt of a 2D CAD model. There were many factors to be considered in deciding the most appropriate route for producing the impellers. These factors mainly involved cost, lead-time, the number of parts required, the final material for the parts, and the part geometry. In order to maximize the benefits in terms of time and cost reduction for the parts, it was decided to use silicon rubber mould and the parts were eventually produced by vacuum casting process. Silicon rubber mould is an easy, relatively inexpensive and fast way to fabricate prototype or pre-production tools. It can be utilized for moulding parts in wax, polyurethane, ABS, and a few epoxy materials. The process is best suited for projects where form, fit, or functional testing can be done with a material which mimics the characteristics of the production material. The casting parts with fine details and very thin walls can be easily and rapidly produced. The whole process flow involved the 3D CAD modelling, producing master pattern (RP prototype), silicon rubber mould, and casting green parts. The time sequence for the fabrication of impellers was described as follows. Due to the complexity of the impeller, the task of generating the 3D CAD model using Pro/Engineer software package took almost 3 calendar days. The master pattern for this project was built on a SPS 600 machine in 2 calendar days. SL process was chosen because it was cost effective and the surface finish was good. The next step involved creating a roomtemperature vulcanized (RTV) silicone rubber mold which was completed within an additional 3 calendar days. Finally, the ABS materials were cast into silicon rubber mould under the vacuum casting condition, and the green parts were achieved in 4 calendar days. The required 30 components were produced successfully and completed in 12 calendar days. The primary process stages are illustrated in Fig. 2. These impellers only cost about 5 thousand RMB and took 12 working days. Consequently, in contrast to the traditional development mode, the impellers developed using the integrated system can cut cost by up to 50% and the time-to-market by 75%. When evaluated against satisfying urgent requirement with respect to time, the procedure is clearly worth pursuing, as indicated by the case study described above. Gong from a 3D CAD solid modeling to fully functional production impellers in less than 12 working days is certainly extraordinary.With proper implementation of the process by qualified personnel, working within the scope of the constraints noted, the acceptance and advancement of the integrated manufacturing methodis likely to grow.3.2. Case study 2: MannequinTen plastic mannequins were required by a client in three months from the receipt of the plaster model of the emulational body. This component was an ideal candidate for using integrated system to development, with a very complex surface and a requirement for only 10 parts. In order to produce the plastic mannequin, the various technologies including reverse engineering, 3D CAD, rapid prototyping and rapid tooling were used to complete model measuring, surfaces reconstructing, 3D CAD modelling, prototype and mould building. The whole development work was presented below. The first step of the project was to construct a CAD model of the emulational body by RE process. ATOS measuring equipment made in GOM Inc. which has a high scanning (10,000 points/sec) and can measure models in a wide range from 500mm to 10mm, was employed to capture the digitized data of the plaster mold. Figure 3(a) shows the point clouds of the body model. The subsequent process was to perform surfaces reconstructing. To speed this process, a special reverse engineering program, called CopyCAD (DelcamInc.), was used to create quickly and easily the CAD surfaces from the digitized data. After surfaces reconstructing, many errors in the original model and the joints must be modified by PowerShape software package (another software of Delcam Inc.). The surfaces model of the body is represented in Fig. 3(b). To fabricate easily, the surface model was divided into 11 individual components which included the head, body, upper arms, forearms, tights, shanks and feet using Pro/Engineer software package. Subsequently, every surface model was converted to a solid model, and many holes and slots needed to be designed for fixing joints such as shoulder, knees, etc. Then, the solid parts and joints were assembled to form the solid model of the emulational body. Figure 3(c) illustrates the completed CAD solid model. The RP prototypes of these components were built on a LPS 600 machine. The assembly RP body model is shown in Fig. 3(d). In addition, silicon rubber moulds of these components were fabricated for producing the green parts. Finally, the required 10 plastic mannequins were produced successfully and the project was completed in about 12 weeks. Figures 3(e) and (f) describe respectively the silicon rubber mould of half head and the green product. The case indicates the rapid development of large product and complex surfaces can be realized quickly following the integrated development mode.4. ConclusionIn this paper, we have presented an integrated system based on RP for rapid product developing. The system consists of four modules: digital prototype, virtual prototype, physical prototype and rapid tooling. It employs fully and integrates closely the various advanced manufacturing technologies which involve the 3D CAD, RE, CAE, RP, and RT. In this system, the procedure of development from design to end product is worked step by step: design, analysis, rapid prototype and tooling. By evaluating the whole process and its various components, and comparing them with traditional process, it has been clear that one can reap benefits in various ways. The system can effectively compress the design and manufacturing cycle time and reduce the development cost, which is an important factor in competition. Using this integrated system to develop new product shows a high potential for faster response to market and customers’ demands. As a result, it will play a more and more important role to reduce the manufacturing cycle and cost of product development in the future.

附录英文文献翻译Drive axle/differentialAll vehicles have some type of drive axle/differential assembly incorporated into the driveline. Whether it is front, rear or four wheel drive, differentials are necessary for the smooth application of engine power to the road.PowerflowThe drive axle must transmit power through a 90° angle. The flow of power in conventional front engine/rear wheel drive vehicles moves from the engine to the drive axle in approximately a straight line. However, at the drive axle, the power must be turned at right angles (from the line of the driveshaft) and directed to the drive wheels.This is accomplished by a pinion drive gear, which turns a circular ring gear. The ring gear is attached to a differential housing, containing a set of smaller gears that are splined to the inner end of each axle shaft. As the housing is rotated, the internal differential gears turn the axle shafts, which are also attached to the drive wheels.Figure 11Component parts of a typical driven axle assembly.Differential operationThe differential is an arrangement of gears with two functions: to permit the rear wheels to turn at different speeds when cornering and to divide the power flow between both rear wheels.The accompanying illustration has been provided to help understand how this occurs. The drive pinion, which is turned by the driveshaft, turns the ring gear (1).The ring gear, which is attached to the differential case, turns the case (2).The pinion shaft, located in a bore in the differential case, is at right angles to the axle shafts and turns with the case (3).The differential pinion (drive) gears are mounted on the pinion shaft and rotate with the shaft (4). Differential side gears (driven gears) are meshed with the pinion gears and turn with the differential housing and ring gear as a unit (5).The side gears are splined to the inner ends of the axle shafts and rotate the shafts as the housing turns (6).When both wheels have equal traction, the pinion gears do not rotate on the pinion shaft, since the input force of the pinion gears is divided equally between the two side gears (7).When it is necessary to turn a corner, the differential gearing becomes effective and allows theaxle shafts to rotate at different speeds (8).As the inner wheel slows down, the side gear splined to the inner wheel axle shaft also slows. The pinion gears act as balancing levers by maintaining equal tooth loads to both gears, while allowing unequal speeds of rotation at the axle shafts. If the vehicle speed remains constant, and the inner wheel slows down to 90 percent of vehicle speed, the outer wheel will speed up to 110 percent. However, because this system is known as an open differential, if one wheel should become stuck (as in mud or snow), all of the engine power can be transferred to only one wheel. Figure 12Overview of differential gear operating principles.Limited-slip and locking differential operationLimited-slip and locking differentials provide the driving force to the wheel with the best traction before the other wheel begins to spin. This is accomplished through clutch plates, cones or locking pawls.The clutch plates or cones are located between the side gears and the inner walls of the differential case. When they are squeezed together through spring tension and outward force from the side gears, three reactions occur. Resistance on the side gears causes more torque to be exerted on the clutch packs or clutch cones. Rapid one wheel spin cannot occur, because the side gear is forced to turn at the same speed as the case. So most importantly, with the side gear and the differential case turning at the same speed, the other wheel is forced to rotate in the same direction and at the same speed as the differential case. Thus, driving force is applied to the wheel with the better traction.Locking differentials work nearly the same as the clutch and cone type of limited slip, except that when tire speed differential occurs, the unit will physically lock both axles together and spin them as if they were a solid shaft.Figure 13Limited-slip differentials transmit power through the clutches or cones to drive the wheel having the best traction.Identifying a limited-slip drive axleMetal tags are normally attached to the axle assembly at the filler plug or to a bolt on the cover. During the life of the vehicle, these tags can become lost and other means must be used to identify the drive axle.To determine whether a vehicle has a limited-slip or a conventional drive axle by tire movement, raise the rear wheels off the ground. Place the transmission in PARK (automatic) or LOW (manual), and attempt to turn a drive wheel by hand. If the drive axle is a limited-slip type, it will be very difficult (or impossible) to turn the wheel. If the drive axle is the conventional (open) type, the wheel will turn easily, and the opposing wheel will rotate in the reverse direction.Place the transmission in neutral and again rotate a rear wheel. If the axle is a limited-slip type, the opposite wheel will rotate in the same direction. If the axle is a conventional type, the opposite wheel will rotate in the opposite direction, if it rotates at all.Gear ratioThe drive axle of a vehicle is said to have a certain axle ratio. This number (usually a whole number and a decimal fraction) is actually a comparison of the number of gear teeth on the ring gear and the pinion gear. For example, a 4.11 rear means that theoretically, there are 4.11 teeth on the ring gear for each tooth on the pinion gear or, put another way, the driveshaft must turn 4.11 times to turn the wheels once. Actually, with a 4.11 ratio, there might be 37 teeth on the ring gear and 9 teeth on the pinion gear. By dividing the number of teeth on the pinion gear into the number of teeth on the ring gear, the numerical axle ratio (4.11) is obtained. This also provides a good method of ascertaining exactly which axle ratio one is dealing with.Another method of determining gear ratio is to jack up and support the vehicle so that both drive wheels are off the ground. Make a chalk mark on the drive wheel and the driveshaft. Put the transmission in neutral. Turn the wheel one complete turn and count the number of turns that the driveshaft/halfshaft makes. The number of turns that the driveshaft makes in one complete revolution of the drive wheel approximates the axle ratio.Figure 14The numerical ratio of the drive axle is the number of the teeth on the ring gear divided by the number of the teeth on the pinion gear.译文：驱动桥/差速器所有的车辆有一些类型的驱动桥/差速器总成包含在传动系统中。

Forging craft not when produces flaw1.Big crystal grainhyperpyrexia and the distortion degree insufficiency, or the end hammers the hyperpyrexia, or the distortion degree falls the human critical deformation range to cause. Aluminum alloy distortion degree oversized, forms the texture; Also the heat-resisting alloy distortion temperature excessively is low, forms when the mix distortion organization possibly causes the thick crystal grain2.The crystal grain is non-uniformThe crystal grain non-uniform is refers to forging certain spots the crystal grain to be specially thick, certain spots are actually small. Has the crystal grain non-uniform primary cause is semifinished materials each place distortion causes the crystal grain stave degree non-uniform not one, either the partial region distortion degree falls the human critical deformation range, either heat-resisting alloy partial work hardening, either when quenching heating the partial crystal grain is thick. High-temperature steel and heat-resisting alloy to crystal grain non-uniform specially sensitive. The crystal grain non-uniform will cause the forging the lasting performance, the weary performance to drop obviously.3.Chilling phenomenonWhen distortion because the temperature somewhat low or the distortion speed too is quick, as well as hammers the after-cooling excessively quickly, possibly causes the conditioning which the recrystallization causes not to be able to follow the strengthening which the distortion causes (hardening), after thus caused the hot forging the forging interior still the part retention cold-work organization. This kind of organization's existence enhanced the forging intensity and degree of hardness, but reduced the plasticity and toughness. The serious chilling phenomenon possibly causes the forging crack, sees example 78, 79, 83, 84.4.CrackThe crack is usually when forging has the big tensile stress, the shear stress or the additional tensile stress causes. The crack occurs the spot usually is biggest in the semifinished materials stress, the thickness thinnest spot. If the semifinished materials surface and the interior have the micro crack, or in the semifinished materials have the organization flaw, either hot-working temperature not when causes the material plasticity to reduce, either distortion speed excessively quickly, distortion degree oversized, surpasses the material permission the plastic indicator and so on, then in removes thick, pulls out long, the punch holes, the broaching, curving and working procedures and so on in extrusion all possibly produces the crack.5.ChapThe chap is presents the shallow turtle shape crack in the forging surface. In the forging forming the tension stress surface (e.g., fill has not protruded part or curving part) easiest to produce this kind of flaw. Causes the chap internal cause possibly is various:①Raw material gathers fusible elements and so on the Cu, Sn excessively are many.②When high temperature long time heating, the steel materials surface has the copper to separate out the surface which, the superficial crystal grain thick, the decarbonization, or passes through heats up many times.③The fuel measures including the sulfur excessively high, has the sulfur to infiltrate the human steel materials surface.6.Edge crackThe edge crack is when the drop forging and the cutting edge produces the crack in a minute modular surface place. The edge crack produces the reason possibly is:①In drop forging operation because hits hard causes the metal intense flowing to produce puts on the muscle phenomenon.②The magnesium alloy die forged item cutting edge temperature excessively is low; Copper alloy die forged item cutting edge hyperpyrexia.7.Minute modular surface crackThe minute modular surface crack refers to the crack which produces along a forging minute modular surface. Raw material mixes with nonmetallic many, when drop forging to divides the modular surface flowing and the centralism or the pipe remaining after the drop forging pushes the human edge often the shape ingredient modular surface crack.8.FoldThe fold was in the flow of metal process has oxidized the surface layer metal converged to form together. It may be (or multi-stocks) the metal convection convergence forms by two; Also might be the massive flowing is close to the part rapidly by a metal the surface layer strap flowing, both convergence will form; Also may be because the distortion metal has, the backflow curving forms; Also may be the partial metal local distortion, is oppressed others in another part of metals to form. Folding and raw material and semifinished materials shape, mold design, formed working procedure arrangement, lubrication situation and forging actual operation and so on related Not only the fold reduced the components load bearing area, when works because here stress concentration often becomes the weary source9.Puts on the classPuts on the class is the streamline distributes the improper one form. Is putting on flows the area, has certain angle distribution the streamline to converge originally to form together puts on the class, possibly and causes to put on flows the area inside and outside grain size difference to be disparate. Puts on the reason which the class produces with the fold to be similar, is by two metals or strap, but puts on flows the part which another metal affluxes form the metal still was a whole puts on the class to cause the forging mechanics performance to reduce, when puts on especially flows the belt both sides crystal grain difference is disparate, the performance reduces obviously.10.The forging streamline distribution is not suitableThe forging streamline distribution along is not refers on forging low time has streamline disorder phenomena and so on streamline cut-off, backflow, turbulent flow. If the mold design does not work as or the forging method choice is unreasonable, prefabricated semifinished materials streamline disorder; The worker does not operate when and the mold wears causes the metal to produce the non-uniform flowing, all may cause the forging streamline distribution not to be suitable. The streamline along cannot cause each mechanics performance to reduce, therefore regarding the important forging, all has the request which the streamline distributes.11.The casting organization remainsThe casting organization remains mainly appears in uses the ingot casting to make the semifinished materials in the forging. The cast condition organization mainly remains in the forging difficult deformation range. Forging compared to insufficient and forging method not when is the primary cause casting organization which the casting organizationremains produces remains can cause the forging the performance drop, attacks the tenacity and the weary performance in particular and so on.12.Carbide segregation rank not symbol requestThe carbide segregation rank symbol request mainly does not appear in the Lai body labor molding tool steel. Mainly is in the forging carbide distributes non-uniform, assumes the greatly massive centralism distribution or assumes the netted distribution. Creates this kind of flaw the primary cause is raw material carbide segregation rank is bad, adds it changes hammers when hammers compared to insufficient or the forging method not when has this kind of flaw forging, when heat treatment quenching easy partial superheat and quenches the crack. Makes the cutting tool and the mold use when easy breaking and so on.13.Banded structureThe banded structure is the ferrite and the pearlyte, the ferrite and the austenite, the ferrite and the bainite aswell as the ferrite and the martensite assumes the belt-shaped distribution in the forging one kind of organization, they appear in Asia altogether fold in the steel, the austenite steel and half martensite steel. This kind of organization, is when which the banded structure which two coexists in the situation forges distortion produces to be able to reduce the material the crosswise plastic indicator, specially resilience. Often is easy in forging either the components work along the lines of ferrite or two intersection point dehiscence.14.Partial backfill insufficiencyThe partial backfill insufficient mainly occurs in the muscle rib, the convex angle, the corner, the fillet spot, the size does not conform to the pattern requirement. Produces the reason possibly is:①The forging temperature is low, the metal fluidity is bad;②The equipment tonnage insufficient or the hammer strength is insufficient;③The system molds the design not to be unreasonable, the semifinished materials volume or the section size are unqualified;④In the mold chest cavity piles up the oxide skin or the welded together distortion metal.15.Owes the pressureOwes the pressure to refer is vertical increases, the reason to the minute modular surface direction size which produces possibly is generally:①The forging temperature is low.②The equipment tonnage is insufficient, hammer strength insufficiency or hammer number of times insufficient16.Wrong movesWrong moves is the forging is opposite along the minute modular surface upper half in the lower part has the displacement. Produces the reason possibly is:①Slide (hammer head) and between guide rail gap oversized;②The forging die design is unreasonable, lacks eliminates wrong moves the strength to close up an opening or the guide pillar;③Mold installment not good17.The spool thread is curvingThe forging spool thread is curving, has the error with the plane geometry position. Produces the reason possibly is:①The forging leaves when the mold does not pay attention;②When cutting edge the stress is uneven;③The forging cools when various part of temperature decrease speed not one;④The cleaning up and the heat treatment improper锻造工艺不当产生的缺陷1.大晶粒大晶粒通常是由于始锻温度过高和变形程度不足、或终锻温度过高、或变形程度落人临界变形区引起的。

U n i t1M e t a l s金属The use of metals has always been a key factor in the development of the social systems of man. Of the roughly 100 basic elements of which all matter is composed, about half are classified as metals. The distinction between a metal and a nonmetal is not always clear-cut. The most basic definition centers around the type of bonding existing between the atoms of the element, and around the characteristics of certain of the electrons associated with these atoms. In a more practical way, however, a metal can be defined as an在人类社会的发展中，金属的应用起着关键性的作用。
构成物质的大约100种基本元素中，大约有一半为金属。
金属和非金属之间的区别不是特别明显。
最基本的定义集中在元素原子间存在的连接形式和与这些原子相关联的电子的某些特性。
然而，在实际应用中，可以将具有某些特性集合金属定义为某种元素。
除了少数例外金属在常温下是固态的。
它们是热和电的良导体，不透光。
它们往往具有较高的密度。
许多金属具有延展性，也就是说，在不被破坏的情况下它们的形状在外力的作用下可以发生变化。
引起永久变形所需的力和最终使金属断裂所需的力相当大，尽管发生断裂所需的力远element which has a particular package of properties.Metals are crystalline when in the solid state and, with few exceptions (e.g. mercury), are solid at ambient temperatures. They are good conductors of heat and electricity and are opaque to light. They usually have a comparatively high density. Many metals are ductile-that is, their shape can be changed permanently by the application of a force without breaking. The forces required to cause this deformation and those required to break or fracture a metal are comparatively high, although, the fracture forces is not nearly as high as would be expected from simple 没有像所预期的撕开金属原子所需的力那么大。

外文原文Differential shell process and boring tooling design The motor car engine power transmission shaft and the clutch, and finally to drive around again assigned half shaft drive wheels, in this article, the drive power transmission way, it is the final assembly of the main parts is reducer and differential. Gear reducer is increased, the function of torque and completely on gear meshing gears, between are easy to understand. But more difficult to understand differential, what, why "differential differential"?The car is driven car differential main parts. It is in the power of both half shaft transmission shaft, allowing both half with different speed spinning wheels, satisfy both pure rolling form as possible, reducing equi-distant not tire and ground friction.Spider diagramObject graph theory differentialfunctionalAt the turn of the car wheel track line, if the car is circular arc, turn left at the center, and at the same time, the wheels went arc length, the wheels than to balance the difference, left, and right wheel wheels slowlySlip differentialFaster, with different speed up the distance.If you make a whole after wheel, can accomplish on both sides of the wheel speed difference, is also does not have an automatic adjustment. In order to solve this problem, a hundred years ago, France Renault automotive company founderluis Renault will design a differential this thing.Slip differentialconstituteOrdinary differential planetary wheel planetary gear, by plane (d ifferential shell), half axle gear parts etc. The power of the engine into the differential transmissionStructurePlanetary wheel frame, driven directly by the planets wheel driv e, right and left two half shaft, wheel drive left and right. Meet the design requirements of differential (left) and the shaft speed (right) = 2 (axial rotational speed) planet round frame. When the car goe s, left, right wheel and planetary wheel frame of equal speed, and in a state of equilibrium in the balance among car when turning ro und to destruction, reduce the speed, the wheel speed increase.StructurePrincipleThis adjustment is automatic differential here, involves "minimal energyconsumption principle", namely earth all objects are tend to minimum energy. Such a grain of beans in a bowl, beans will automatically stays in the bowl bottom and never stay in the bowl wall, because the bowl bottom is the lowest energy (potential), it automatically select static (minimum) without energy. In the same way,A 3d effectWheel in turning also will be the lowest power consumption tendency, automatically adjusted according to turn radius of the wheel speed around.When turning wheel, because the pull of the phenomenon, the medial wheel slip phenomenon, two driving wheel at will produce two opposite direction of additional force, due to the "principle of minimal energy consumption, will inevitably lead to the wheel speed different sides, thus destroyed the balance between three and half shaft are reflected by the half axle gear planetary gears, forced to produce the half shaft rotation speed, speed, the medial axis speed slow speed, so as to realize the difference on both sides wheels.If the drive wheels on both sides of the drive shaft with a whole rigid connection, only two wheels at the same Angle rotation. So, when the steering wheel, due to the lateral than inside the distance moved across the wheels, will make the scroll wheel on the slide, and drag on the scroll wheel inside the slip. Even the car run straight road gravamen, because although flat tire surface or rolling radius (but ranging from manufacturing error, wear different tyres, ranging from uneven pressure or carrying of sliding wheel) and cause.When the wheel sliding tire wear, not only aggravate increased power and fuel consumption, still can make steering difficulties, braking performance deterio rated. As for the wheels, and does not occur in structure sliding must ensure each wheel at different angles can rotate.Axis between differential driven wheels usually use bearing spindle support in the, can at any Angle rotation, and drive wheels with two and half shaft rigid connection, between two and half shaft with differential. The differential and called shaft between differential.Many of the drive shaft, and to make each off-road vehicle drive to different velocity rotating, in order to eliminate the bridge of the drive wheels, some in two axles sliding between between shaft with differential.Differential inspection1 differential shell doesn't have any properties of crack, shell and planetary gear differential half shaft washer, contact between gear, should be smooth without groove, If there is a slight groove or wear, can continue to use after grinding, or should be replaced or be repaired.2 the planetary gear differential shell and planetary gear wheel when the fitting clearance shall not greater than 0.1-0.15 mm, half axle gear shaft neck and shell hole for clearance, with no obvious loose labels should be replaced or feeling, or repair.Shell's processing technologyThe processing quality not only affects shell, the assembly precision and accuracy, but also affects the movement of the machine working accuracy, performance and life.There are many kinds of shell structure, its size and form with the structure of the machine and the shell in machine has the different function. But they rema in on the analysis from the craft had a lot in common and its structure features are:(1) appearance is basically composed of six or five plane again into the closed-end polyhedron, integral and combined two,(2) structure shape is more complex. Inside the cavity is often, some places "partition wall, shell and uneven thickness thin.(3) shell walls are usually decorate have parallel hole or vertical hole,(4) on the shell, main processing is the number of plane, in addition to many higher accuracy and precision of supporting bearing with less demanding tighten pore.Shell parts technical requirements:(1) bearing support size precision and accuracy, surface roughness, requirements,(2) position precision including hole axis of the distance between the dimension precision, the same axis parallel degree in each hole, and KongDuan facing the coaxial tolerance of vertical axis holes; etc.(3) to meet the needs and positioning of the shell processing machine assembly request, shell and assembly of shell with the datum plane positioning due and certain degree, and the surface roughness requirements, The bearing hole and assembling a certain distance between datum due to the accuracy requirement of the size.中文译文差速器壳体工艺及工装设计汽车发动机的动力经离合器、变速器、传动轴，最后传送到驱动桥再左右分配给半轴驱动车轮，在这条动力传送途径上，驱动桥是最后一个总成，它的主要部件是减速器和差速器。
