Unit 1 材料的种类(1)材料的分类方法很多。
科学家常用的典型的方法是根据它们的状态分类:固体,液态或气态。
材料也分为有机(可再生)和无机材料(不可再生)。
(2)工业上,材料划分为工程材料或非工程材料。
工程材料用于制造和加工成零件的材料。
非工程材料是化学药品,燃料,润滑剂和其它用于制造又不用来加工成零件的材料。
(3)工程材料可进一步细分为:金属,陶瓷,复合材料,聚合材料,等。
Metals and Metal Alloys 金属和金属合金金属和金属合(4)金属有好的导电好导热性,很多金属有高的强度,高硬度和高的延展性。
象铁,钴,镍这些金属有磁性。
在非常低的温度下,一些金属和金属互化物变成超导体。
(5)合金和纯金属有什么区别?纯金属在元素周期表的特殊区域。
例如用于制造电线的铜和做锅和饮料罐的铝。
合金含有两种以上的金属元素。
改变金属元素的比例可以改变合金的性质。
例如,合金金属的不锈钢,是由铁,镍,和铬组成。
而黄金珠宝含有金镍合金。
(6)为什么要使用金属和合金?很多金属和合金有很高密度并用在要求质量与体积比高的的场合。
一些金属合金,象铝基合金,密度低,用在航空领域可以节省燃料。
很多合金有断裂韧度,可以承受冲击,且耐用。
金属有哪些重要属性?(7)【密度】质量除以体积叫做密度。
很多金属有相对高的密度,特别的,象聚合体。
高密度的材料常是原子量很大,象金或铅。
然而一些金属,像铝或镁密度低,就常常用在要求有金属特性而又要求低质量的场合。
(8)【断裂韧性】断裂韧度用来描述金属抗断裂的能力,特别的,当有裂纹时。
金属通常都有无关紧要的刻痕和凹坑,且有耐冲击性。
足球队员关注这一点当他确信面罩不会被击碎的时候。
(9)【塑形变形】塑性变形表述的是材料在断裂之前弯曲变形的能力。
作为工程师,我们通常设计材料使得能够在正常情况下不变形。
你不会想要一阵强烈的西风就把你的车刮得往东倾斜。
然而,有时,我们可以利用塑性变形。
汽车的承受极限就是在彻底破坏之前靠塑形变形来吸收能量。

Basic Concept in MechanicsThe branch of scientific analysis which deals with motions , time , and forces is called mechanics and is made up of two parts , statics and dynamics , Statics deals with the analysis of stationary systems , i.e. , those in which time is not a factor , and dynamics deals with systems which change with time .对运动、时间和作用力做出科学分析的分支称为力学。
它由静力学和动力学两部分组成。
静力学对静止系统进行分析,即在其中不考虑时间这个因素,动力学对随时间而变化的系统进行分析。
When a number of bodies are connected together to form a group or system , the forces of action and reaction between any two of the connecting bodies are called constraint forces . These forces constrain the bodies to behave in a specific manner . Forces external to this system of bodies are called applied forces .当一些物体连接在一起形成一个组合体或者系统时,任何两个相连接的物体之间的作用力和反作用力被称为约束力。
这些力约束着各个物体,使其处于特定的状态。
从外部施加到这个物体的系统的力被称为外力。

1.With low-power machinery or vehicles the operator can usually apply sufficient force through a simple mechanical linkage from the pedle or handle to the stationary part of the brake. In many cases, however, this force must be multiplied by using an elaborate braking system.(P5)用低能机器或传力工具,操作者通过向踏板或把手的一个简单机械连接构件作用足够的力量到车闸固定的部分。
大多数情况,然而,用一个详细(复杂)的车闸系统使这个力量成倍增加。
2. The fundamental principle involved is the use of compressed air acting through a piston in a cylinder to set block brakes on the wheels. The action is simultaneous on the wheels of all the cars in the train. The compressed air is carried through a strong hose from car to car with couplings between cars; its release to all the separate block brake units, at the same time, is controlled by the engineer. (Braking Systems)(P5)相关的基本原理是使用压缩气体,通过气缸内的活塞将闸块压在车轮起作用。
列车的所有车厢上的车轮同时动作。
压缩气体通过一个坚固的管道在由联轴器连接的车厢之间传输;工程师控制其在同一时间释放到所有独立的闸块单元。
3.When the brake pedal of an automobile is depressed, a force is applied to a piston in a master cylinder. The piston forces hydraulic fluid through metal tubing into a cylinder in each wheel where the fluid’s pressure moves two pistons that press the brake shoes against the drum. (Braking Systems)(P5)当踩下汽车刹车的踏板,在主汽缸中的活塞上施加一个力。
活塞驱动液压流体通过金属管道进入每个车轮气缸,在那里液压移动两个活塞将闸片压向轮圈。
4.Machinery ontology including mechanical rack, mechanical connections and mechanical transmission, which is the basis of mechanical-electrical integration, plays a role in supporting the other functional units of the system and transmitting motion and power. Compared to purely mechanical products, the performance and functionality of integration technology in electrical and mechanical systems have been improved a lot, which requires mechanical ontology to adapt its new status in mechanical structure, materials, processing technology, as well as the areas of geometry. Accordingly, the new ontology is with high efficient, multi-functional, reliable and energy-saving, small, light-weighted and aesthetically pleasing characteristics. (Mechatronics System) (P7)机械体包括机架、机械联接和机械传动,它是机电一体化的基础,作用是支撑系统其他功能单元,传递运动和动力。
和纯机械产品相比,一体化技术的性能和功能在机电系统中大幅提高,它要求机械本体适应在机械结构、材料、加工技术以及这些领域中的几何学下的新环境。
相应的,新的一体化具有高效、多功能、可靠、节能、小轻和美学的令人赏心悦目的特征。
5. Detecting sensor detecting sensor part includes a variety of sensors and signal detection circuit, and its function is to detect the process of mechatronic systems in the work itself and the changes of relevant parameters in external environment and transmit the information to the electronic control unit. Electronic control unit check the information and sends the corresponding control issues to the actuator. (Mechatronics System) (P7)检测传感器部分包括各类传感器、信号检测电路,它的功能是检测机电系统自身工作的工程,在外部环境下的相关参数的改变,将其信息传给电子控制单元。
电子控制单元通过检查信息,送出相应的指令到执行机构。
6. Electronic control unit, also known as ECU, is the core of mechatronic systems, responsible for the external commands and the signals output by sensors. It centralizes stores, computes and analyzes the information. Based on the results of information processing,instruction are issued according to a certain extent and pace to control the destination for the entire system. (Mechatronics System) (P7)电子控制单元,也被称为控制单元(ECU)控制,是机电系统的核心,负责外部命令和传感器的信号输出。
它集中、存储、计算并分析信息。
基于信息处理的结果,按照一定的范围和步调发出命令来实现控制整个系统的目标。
7. It is put into a fairly standard machine tool that has had position sensing and motors on the control knobs installed. This is basically just a robot machinist. You use a rotating cutting tool to cut away all the metal that isn’t your crank. 3D metal etch-a-sketch, with the computer interpolating, so the circles come out to be pretty smooth. (CNC Machining) (P9)将数控系统装入一个非常标准的机床,它在控制手柄上有位置感应和马达。
这基本上是一个机械师。
你能使用一个旋转切削刀具切掉不是你设计的所有金属。
具有计算内插的三维金属蚀刻成型可以使得圆被加工得更光滑。
8. They (CNC machine) are complicated machines, full of servomechanisms, and measuring technology that can measure to 0.005mm (0.0001”) while covered in oil. A CNC machine has a minimum of 6 motors (including some to change tools, and one or more to pump oil and coolant various places). This translates to running costs that may be well over $1/minute. (The computer is not a significant part of the cost any more.) (CNC Machining) (P10)数控机床是复杂的机器,具有伺服机构和检测技术,它能在覆盖油膜状态下检测到0.005mm。
数控机床至少有6个马达(包括一些用来换刀具,一个或多个用来泵油和冷却液的各地方)。
这些化成运行成本可能大大超过1美元/分钟。
(电脑不再是成本的一个重要部分.)9.Systems that can assess if the car is behaving safely can be used to warn drivers that their behavior is unsafe.In more extreme cases,the systems could override the driver and cause the car to stop or slow down.While this would on doubt save lives,it may provide a problem for the makers of films that include car chase---some of the impact may be lost when we live in a word where our cars simply refuse to do anything unsafe.10.Another feature of the work of Dr.Ljubo Vlacic’s team is to have the machines communicate with each other.Since messages can goat the speed of light,it is possible for there to be an exchange of information on the intentions of several machines approaching an intersection.With this knowledge it should be possible to ensure that traffic flows far more smoothly.11. Factory assembly line machinery is activated and monitored by a single PLC, where in the past hundreds of timers and relays would have been required to do the task. The machine or system user rarely, if ever, intera cts directly with the PLCs program. When it is necessary to either edit or create the PLC program, a personal c omputer is usually (but not always) connected to it. (What is aPLC?)用一个 PLC 就能操纵和监控工厂的装配线机械,过去完成同样的工作需要成千的定时器和继电器。
