It is decision making process(often iterative),in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a sated objectives and criteria, synthesis, analysis, construction ,testing, and evaluation. The engineering design component of a curriculum must include most of the following features : development of student creativity, use of open-ended problem statement and use of modern design theory and methodology, formulation of design problem statement and specification, consideration of alternative solutions, feasibility considerations, production process, concurrent engineering design, and detailed system descriptions. Further, it is essential to include a variety of realistic constraints such as economic factors, safety, reliability, aesthetics, ethics, and social impact.31、what’s the main meaning of message (1)?A) Engineering design is a systematic process B) materials engineer’s main workC) mechanical engineer’s has good idea D) electrical engineer’ main duty32、In the author’s opinion, the design process is very complex and should taken intoaccount many factors, from the message who should NOT join into the design team _______.A) environmentalists,B) sociologistsC) engineersD) Government officials33、From the message, we can know the meaning of words “ABET”(at line third paragraph)is _____.A) a set of accredits standardB) a kind of design methodC) a department of US government which responsible for engineering designD) A set of law34、It can be concluded from the passage that in the exercise and training of student,which character of the following is NOT included in the curriculum ______.A) creativityB) new materialC) ethicsD) economic factors35、The title of the message is ______.A) the roles of engineers in manufacturingB) the importance of mechanical designC) engineering designD) The process of machine designTEXT 2Working drawings are the complete set of standardized drawings specifying the manufactureand assembly of a product based on its design. The complexity of the design determines the number and types of drawings. Working drawings may be on more than one sheet and may contain written instructions called specifications.Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely describe the parts, both visually and dimensionally;(b)show the parts in assembly;(3)identify all the parts; and (4)specify standard parts. The graphics and text information must be sufficiently complete and accurate to manufacture and assemble the product without error.共 5 页第 2页(1) Detail drawings of each nonstandard parts.(2) An assembly or subassembly drawing showing all the standard and nonstandard parts in a single drawing.(3) A bill of materials (BOM).(4) A title block.A detail drawing is a dimensioned, multiview drawing of a single part, describing the part’s shape, size, material, and surface roughness, in sufficient detail for the part to be manufactured based on the drawing alone. Detail drawings are produced from design sketches or extracted from 3-D computer models. They adhere strictly to ANSI standards and the standard for the specific company, for dimensioning, assigning part numbers, notes, tolerances, etc.In an assembly, standard parts such as threaded fasteners and bearings are not drawn as details, but are shown in the assembly view. Standard parts are not drawn as details because they are normally purchased, not manufactured, for assembly.For large assemblies or assembled with large parts, details are drawn on multiple sheets, and a separate sheet is used for the assembly view. If the assembly is simple or the parts are small, detail drawings for each part of an assembly can be placed on a single sheet.Multiple details on a sheet are usually drawn at the same scale. If different scales are used, they are clearly marked under each detail. Also,when more than one detail is placed on a sheet, the spacing between detailsTEXT 3One principle aim of kinematics is to create (design) the desired motions of the subjects’ mechanical parts and then mathematically compute the positions, velocities, and accelerations, which those will create on the parts. Since, for most earthbound mechanical systems, the mass remains essentially constant with time, defining the accelerations as a function of time then also defines the dynamic forces as a function of time. Stresses, in turn, will be a function of both applied and inertial (ma) forces. Since engineering design is charged with creating systems which will not fail during their expected service life, the goal is to keep stresses within acceptable limits for the materials chosen and the environmental conditions encountered. This obviously requires that all system forces be defined and kept within desired limits. In machinery, the largest forces encountered are often those due to the dynamics of the machine itself. These dynamic forces are proportional to acceleration, which brings us back to kinematics, the foundation of mechanical design. Very basic and early decision in the design process involving kinematic principles can be crucial to the success of any mechanical design; a design which has poor kinematics will prove troublesome and perform badly.Any mechanical system can be classified according to the number of degree of freedom (DOF) which it processes. The system’s DOF is equal to the number of independent parameters which are needed to uniquely define its position in space at any instant of time.A rigid body free to move within a reference frame will, in the general case, has complex motion, which is a simultaneous combination of rotation and translation. In three-dimensional space, there may be rotation about any axis and also simultaneous translation which can be resolved into components along three axes. In a plane, or two-dimensional space, complex motion becomes a combination of simultaneous rotation about one axis (perpendicular to theplane) and also translation resolved into components along two axes in the plane41、Kinematics research focus on the following EXCEPT ______..A) accelerations B) forceC) positions, D) velocities42、From the passage that for the design engineer the first and most important is____A) the service life of a machine B) the materials chooseC) the degree of freedom D) kinematic principles43、An mechanical system has uniquely defined position in space at any instant of time that ___.A) It should has one DOFB) It should Has two DOFC) the DOF and the number of independent parameters should equalD) It should has any DOF as want44、 which one of the following is NOT TRUE _______?.A) A rigid body free to move in three-dimensional space may rotation about any axisB) A rigid body free to move in three-dimensional space is a simultaneous combinationof rotation and translationC) A rigid body free to move in three-dimensional space can be resolved into componentsalong three axesD) A rigid body free to move in three-dimensional space may has complex motion45、The best title for this passage would be _______.A) kinematics B) dynamicsC) kinematics and dynamic D) the important of kinematics共 5 页第3 页1.将下列英语句子译成汉语(共5小题,每小题2分)(1)A perfectly rigid or inextensible link can exist only as a textbook type of model of a real machine member.(2)Foundations should ensure the machine’s stiffness; shock absorption and isolation are secondary considerations.(3)Thus, if a mechanical component such as a spring is subjected to repetitive or cyclical applications of stress levels much lower than the ultimate strength, it will fracture after a large number of repetitions of this stress.(4)Interchangeability means that identical parts must be interchangeable, i.e., able to replace each other, whether during assembly or subsequent maintenance work; without the need for any fitting operations.(5)A gear can be gripped axially between a shoulder on the shaft and a spacer, with torque being transmitted through a key.2、将下段英语翻译成汉语(10分)As we look around us we see a world full of “things”, machines, devices, tools, things that we have designed, built, and used; things made of wood, metals, ceramics, and plastics. We know from experience that some things are better than others; they last longer, cost less, are quieter, or are ease to use. Ideally , however, every such item has been designed according to some set of “functional requirements” as perceived by thedesigners—that is, it hs been designed so as to answer the question,(5)当一个装置意外地失效后,通常需要进行研究工作,来找出失效的原因和确定可能的改正措施。

mechatronic(机电一体化)机械专业英语
Mechatronic1. IntroductionMechatronics is a design process that includes a combination of mechanical engineering, electronic engineering, material engineering, chemical engineering and industrial engineering. Mechatronics is a multidisciplinary field of engineering, that is to say, it rejects splitting engineering into separate disciplines.Nowadays, with the increasing of economy, Interdisciplinary research becomes an irreversible tendency. Which means mechatronic is facing unprecedented challenges. The old mechanics cannot catch the pace of new world, so they need to be changed. In order to stand steady from the competition, they must provide high value by being innovative during the process of transformation and upgrading.2. Mechatronic system applicationMechatronics are useful on so many fields, such as Machine vision, Automation and robotics, Servo-mechanics and so on.Mechatronic system apply to Machine vision (MV)Mechatronic make the possibilities of MV, technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance in industry, came true.Mechatronic system apply to Automation and roboticsImagine that just push some simple bottoms lightly can you control a huge, smart, intelligent robots. Is it only dreamed? No, it is reality. When mechatronic system applies to automation and robotics we can meet that easily.Mechatronic system apply to Servo-mechanicsCommon type of servo provides position control. Servos are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force. Other types of servos use hydraulics, pneumatics, or magnetic principles. Whatever type it is, it can be separate as feedback system, transducer system and control system. And all of it cannot be kept in functional order without mechatronic system engineering.3. Future challengesMechatronic products -- products that blend mechanical, electrical and software technologies -- have exploded far beyond such industries as high-tech, aerospace and consumer product goods. That means more and more product development teams that once may have been comprised of mechanical engineers and electrical engineers are now adding software to the mix.Multiple engineering disciplines are being challenged to work together in mechatronic product development, such as on this printed circuit board assembly created in PTC's Pro/Engineer.Additional challenges of mechatronic product development noted by PTC include MCAD changes not reaching electrical engineers quickly enough, ECAD designers working ahead of the mechanical engineer and failing to relay that information, and software development largely removed from the product development change management process.。
电子电气专业英语
一、History about electronics(电子技术,电子学,电子设备)1、The English names for the department and the majors电气工程系Department of Electrical Engineering电气化铁道工程Electrified railway engineering电气自动化技术Electrical automation technology电子信息工程技术Technology of electrical and Information Engineering 应用电子技术The application of electronic technology电子工艺与管理Electronic technology and management供用电技术Technology power电机与电器Motor and electric appliances铁道通信信号Railway communication signal2、History about electronicsThere can be no doubt that the 1900s is remembered as the electronic century. Of course there have been other great advances, in medicine(医学领域), in transport, in science, in commerce(商业领域), and many other fields but where would they have been without the instruments and devices that electronics has provided?How would you see a 3D virtual reality image(3D虚拟现实影像) of your beating heart with no electronics? Would you go to a pop concert(流行音乐会)that had no amplifiers(【电子】放大器,扩音器), large screens or lighting effects? Don’t say you would rather watch TV-there would not be any.Electronics in the early 20th century started thriving at a greater speed unlike the pre-20th century developments. The radio(无线电) invented by the Italian genius Marconi and the work of Henry Hertz opened the road to further discoveries and inventions.In the first decade the new thing that was welcome to the technical world was the vacuum tube(真空管,电子管). The vacuum tubes at that time worked as a miraculous component for the radio devices.The invention of the television was a miraculous thing for the mankind. It was revolution in both communication technology(通信技术) and also for the world media. The distances between the continents did not seem to be far enough.The credit goes to the British engineer John Logic Baird who followed the footprints of Marconi and tried to send the images in the same way as the speech. After a long experiment he found that a series of static pictures, if sent within a small interval of time in between them, seem to be moving.The real electronics what it is called today was actually started after the discovery of the transistor(晶体管) effect. Transistor opened the road for the computing world. Computers of various types started hitting the market and the research works got a boost.Some other problems were also there like the assembling(装配,聚集) of the electronic components(电子元器件) on a single mother board(母板,主插件板). Jack Kilby in Texas Instruments found a very nice solution.He suggested to throw away all the wires(wire:电线,电报) and tried to connect the resistors(电阻器), capacitors(电容器) and transistors on the samepiece of wafer(圆片,晶片) internally. Surprisingly his ideas worked and gave birth to the integrated circuit(集成电路) industries.二、Introduction to some courses1、Direct current circuits & Alternating current circuits(直流电路与交流电路)This course covers the fundamental theory of passive devices (无源器件)(resistor, capacitor, and inductor(电感器)) and electrical networks(电子、电路网络) supplied by a DC source(直流电源), then an introduction to the effects of alternating voltage and current in passive electrical circuits(electrical circuit:电路)is given. This module also covers DC machines, three phase circuits(三相电路)and transformers(变压器).这门课程包括了无源器件(电阻,电容和电感)的基本理论和用直流电源供电的电路网络,接着介绍无源电路中的交流电流和交流电压的作用,这个课程模块还包括了直流电机,三相电路和变压器。

( T )6、If a sinusoidally varying voltage source is connected across the capacitor, it can be shown that the voltage across the capacitor lags the current by in phase, meaning that the voltage peaks occur 1/4 of an oscillation period later in time relative to the current peaks.如果一个以正弦波形式随时间正负变化的电压源加在电容上,将会使电容电压在相位上滞后于电流,即该电压的峰值会比电流的峰值晚出现四分之一个周期的时间。
机电工程专业英语
1The rotor (rotating member) in an electric motor has rotational inertia, and a torque is required to bring it up to speed when the motor is started. If the motor shaft is rigidly connected to a load with a large rotational inertia, and the motor is started suddenly by closing a switch, the motor may not have sufficient torque capacity to bring the motor shaft up to speed before the windings in the motor are burned out by the excessive current demands . A clutch between the motor and the load shafts will restrict the starting torque on the motor to that required to accelerate the rotor and parts of the clutch only.电机的转子(转动元件之一)是有惯性的。
当电机启动时,需要一个力矩使转子提升速度。
如果电机轴与负荷是刚性连接,就会有更大的惯性。
这样启动,电机在还没有足够的力矩使转子提升到一定速度,可能就被过电流烧毁了线圈。
在电机和负荷之间的离合器,会限制启动转矩来保证有足够的力矩只加速转子和离合器。
有些机床,可以非常方便的在电机连续运转时,通过操作离合器来启动或停止机器的。
2To keep the parts separated, it is necessary that the pressure within the lubrication film balance the load on the sliding surfaces. If the lubricating film’s pressure is supplied by an external source, the system is said to be lubricated hydro-statically. If the pressure between the surfaces is generated as a result of the shape and motion of the surfaces themselves, however, the system is hydro-dynamically lubricated. This second type of lubrication depends upon the viscous properties of the lubricant.为了把零件隔离开,润滑膜中的压力必须和作用在滑动面上的负载(荷)保持平衡。

With the advent of computers and machines that can be controlled by computers, we are entering a new era of production planning. The integration of the design function and the manufacturing function through the computer is called CDA/CAM. The design is used to determine the manufacturing process planning and the programming information for the manufacturing processes themselves. Detailed drawings can also be made from the central data base used for the design and manufacture, and programs can be generated to make the parts as needed. In addition, extensive computer aided testing and inspection (CATI) of the manufactured parts is taking place. There is no doubt that this trend will continue at ever-accelerating rates as computers become cheaper and smarter.
