1.机械设计过程 机械设计的最终目标是生产一种满足客户需求的有用产品,而且这种产品安全,高效,可靠,经济,实用。当回答这个问题时,广泛地思考,我将要设计的产品或系统的客户是谁? 在产品设计之前,了解所有客户的期望和期望是至关重要的。营销专业人员经常被用来管理客户期望的定义,但是设计师可能会把他们作为产品开发团队的一部分。 许多方法被用来确定客户想要什么。一种被称为质量功能部署或QFD的流行方法寻求(1)识别客户期望的所有特征和性能因素,以及(2)评估这些因素的相对重要性。QFD过程的结果是产品的一组详细功能和设计要求。 考虑设计过程如何配合为客户提供令人满意的产品所必须发生的所有功能以及在产品的整个生命周期中为产品提供服务也很重要。事实上,重要的是考虑产品在使用寿命后如何处置。影响产品的所有这些功能的总和有时被称为产品实现过程或PRP。PRP中包含的一些因素如下: ?营销功能来评估客户的要求 ?研究确定可在产品中合理使用的可用技术 ?可以包含在产品中的材料和组件的可用性 ?产品设计和开发 ?性能测试 ?设计文件 ?供应商关系和采购职能 ?考虑全球材料采购和全球营销 参加工作的技能 ?物理工厂和设施可用

?制造系统的能力 生产计划和生产系统的控制 ?生产支持系统和人员 ?质量体系要求 ?销售操作和时间表 ?成本目标和其他竞争性问题 ?客户服务要求 ?产品在生产,操作和处置过程中的环境问题 ?法律要求 ?金融资本的可用性 你可以添加到这个列表吗?您应该能够看到,产品的设计只是综合过程的一部分。在本文中,我们将更加注意设计过程本身,但必须始终考虑设计的可生产性。产品设计和制造过程设计的同时考虑通常被称为并行工程。 2.机械设计所需的技能 产品工程师和机械设计师在日常工作中使用广泛的技能和知识。这些技能和知识包含在以下内容中: ?素描,技术制图和计算机辅助设计 ?材料的性质?材料加工*和制造过程 ?化学的应用,如腐蚀防护,电镀和喷漆 静力学动力学材料的强度,运动学和机制 流体力学,热力学和传热 ?流体动力,电气现象的基本原理和工业控制

机械工程专业英语

Lesson1 1、the 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作出科学分析的分支成为力学。他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引述,动力学对事件而变化的系统进行分析。 2、Any two such forces acting on a body constitute a couple. The arm of the couple is the perpendicular distance between their lines of action, and the plane of the couple is the plane containing the two lines of action. 作用在一个刚体上的两个这样的的里构成一个力偶。力偶臂是这两个条作用线之间的垂直距离,力偶面是包含着两条作用线的平面。 3、Mechanics deal with two kinds of quantities: scalars and vectors. Scalar quantities are those with which a magnitude alone is associated. Examples of scalar quantities in mechanics are time, volume, density, speed, energy, and mass. Vector quantities, on the other hand, possess direction as well as magnitude. Examples of vectors are displacement, velocity, acceleration, force, moment, and momentum. 力学涉及两种类型的量,标量和矢量。标量是那些只有大小的量。在力学中标量的例子有时间、体积、密度、速率、、能量和质量。另一方面,矢量既有大小又有大小又有方向。矢量的例子有位移、速度、加速度、力、力矩、动量。 Lesson2(此课后面没翻译,翻译的不太准确谅解) 1 、The turning of a part in a lathe is another example of several forces in action.(as shown in figure1) 车床车削是一些力在起作用的另一个例子。figure1(如图)。 2 、If this workpiece is held between the centers of the lathe, the centers exert a compressive force against the work. 如果这个工件在放在车床中心之间,中心车床对工作产生压力。 3、 Rotary motion is required to drill holes, turn parts in a lathe, mill surfaces, or drive a generator or fan belt. 扶轮运动需要去钻孔,在车床上转换两件,表面,或驱动发电机或风扇皮带 4 、Harmonic and Intermittent Motion(谐和运动和间歇运动): Any simple vibration, such as the regular back, and forth movement of the end of a pendulum, is simple harmonic motion. Lesson4 1 、Virtually all machines contain shafts. The most common shape for shafts is circular and the cross section can be either solid or hollow. 实际上,几乎所有的机器中都装有轴。轴的最常见的形状是圆形,其截面可以是实心的,也可以是空心的(空心轴可以减轻重量)。有时也采用矩形轴,例如,螺丝起子的头部.套筒扳手和控制旋钮的杆。 2、 A shaft must have adequate torisonal strength to transmit torque and not be over stressed it must also be torsional stiff enough so that one mounted component does not deviate excessively from its original angular position relative to a second component mounted on the same shaft. 为了在传递扭矩时不发生过载,轴应该有适当的抗扭强度。轴还应该具有足够的抗扭强度,以使在同一轴上的两个传动零件之间的相对转角不会过大。 3 、Components such as gears and pulleys are mounted on shafts by means of key. The design of the key and the corresponding keyway in the shaft must be properly evaluated. For example, stress concentrations occur in shafts due to keyways, and the material removed to from the keyway further weakens the shaft. 齿轮和皮带轮等零件通过键连接在轴上。在键及轴上与之相对应的键槽的设计中,必须进行认真的计算。例如,轴上的键槽会引起应力集中,由于键槽的存在会使轴的横截面积减小,会进一步减弱轴的强度。 4、Another important aspect of shaft design is the method of directly connecting one shaft to another. Devices such as rigid and flexible couplings accomplish this. 轴的设计工作中的另一个重要方面是一根轴与另一根轴之间的直接连接方法。这是由刚性或者弹性联轴器来实现的。 Lesson5 1、The term shaft usually refers to a relatively long member of round cross section that rotates and

机械五班王乘龙 Lesson 25 Computer Graphics(Reading Material) The term computer graphics refers to the entire spectrum of drawing with the aid of a computer,from straight lines to color animation.An immense range of artistic capabilities resides under the heading of computer graphics and drafting is just one of them. Computer graphics was originally associated with the field of electronics.Companies directly involved in electronics design and manufacturing were the first to experiment and work with computer graphics.As they tested equipment and software,new demands arose that required changes and advances in both hardware and software.Equipment and programs got better,faster,more powerful,less expensive,colorful,and fun to operate.The potential for this new computer development was endless.And as engineers and drafters learned to work with the new tools in a technically demanding atmosphere,artists were using the new tools in an atmosphere of unlimited structure.We see the structure and freedom brought by engineers and artists to computer graphics as we watch animated television network.Complex mathematical

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。一特定形式的适用于大范围的工程材料至少工程材料受载荷的大部分的弹性, 产生正比于负载的变形。由于载荷正比于载荷所产生的压力并且变形正比于应变, 这也说明,当材料是弹性的时候, 应力与应变成正比。因此胡克定律陈述, 应力正比于应变。 这定律服从于大部分铁合金在特定的范围内, 甚至以其合理的准确性可以假定适用于其他工程材料比如混凝土,木材,非铁合金。 当一个材料是弹性的时候,当载荷消除之后,任何负载所产生的变形可以完全恢复,没有永久的变形。

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.

. 4、工程机械概述 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, look better, or are easier to use. ; ; 情况 . Ideally, however, every such item has been designed according to some set of “functional requirements”as perceived by the designers—that is, it has been designed so as to answer the question,“Exactly what function should it perform?” In the world of engineering, the major function frequently is to support some type of loading due to weight, inertia, pressure, etc. 的 From the beams in our homes to the wings of an airplane, there must be an appropriate melding of materials,dimensions, and fastenings to produce structures that will perform their functions reliably for a reasonable cost over a reasonable
