附 录 A 外文文献原文 Chinas engineers and users also stay in QianPan HouGu on the idea, and, before and after the application of the disc brake is commercial vehicle braking performance increase the optimal scheme. Because HouGu type brake on the temperature, the braking performance is very big, lead to the front axle attenuation disc brakes to bear on the part of the load, cause too much of the disc brake, brake piece of life of overload shorter. For cars in the braking process, because the role of the front, inertial load always takes all the car load 70% 80%, so the front wheel brake force to than the rear wheels. Manufacturers to cut costs, use the front disc brake, rear wheel drum brake mix of matching method. The QianPan HouGu type mixed brake, this is mainly due to the cost considerations. With the rapid development of Chinas national economy, the average consumer safety and environmental requirements of cars is increasing day by day, the miniature car industry from tiny truck started, the transition to tiny coaches, and then promoted to use tiny cars as transport, become the necessity of historical development; On the other hand, all miniature car companies already will capital and power steering mini car industry, to adapt to the different needs of consumers out mini car products, some private enterprises will also mini car into the breach of the car market as, constantly of price war, make mini car prices have no longer too high, and began to close to ordinary people. Disc brake caliper disc and main overall type two kinds, modern car on the application of the most caliper disc brake, it is the rotation of the element is brake disc, fixed element is brake caliper. And, according to the brake caliper movement way and can be divided into set caliper disc brake, sliding caliper disc brake caliper disc brake and, including sliding caliper disc brake application more widely. The working principle of caliper disc brake is similar to a bicycle brake, braking process, the brake caliper will brake piece of extrusion to brake disc, along with the brake disc and lining block of the friction between the gradually will fall speed. And sliding caliper disc brake is brake caliper can be relatively brake disc axial sliding; Only in the inside of the brake disc set oil cylinders, and the outside of the brake block is in the grips attached on the body. Disc brakes in use process, also can appear fault, among them the more common wind resistance, underpowered and brake system has noise etc. ntsDisc brake parts of fever in a narrow focus on the brake lining block, the unit and pressure than drum brakes, brake lining large block and clamp body of the piston direct contact with, so the quantity of heat of braking extremely easily to the brake fluid. So, make disc brakes easy to produce gas resistance phenomenon. But, if take corresponding measures, also can prevent air resistance happens. Miniature and affordable in our country are big car market, in recent years the domestic demand expansion drive the car market demand for miniature of the increase. Authorities say Chinas economy has entered into the platform, the moderate growth will pull the stable growth of car market. Last year, Chinese each enterprise benefits to improve, per capita disposable income increase, cause individual needs to improve the car; Countries carrying out the strategy for western development, to WeiChe market is tremendous potential demand of no doubt. From 0.9 to 1.6 L L, the price is suitable for Chinas national conditions, suitable for the current status of the development of the China is. Automobile brake clamps body stent is one of important parts, along with the car now design processing development of manufacturing technology, the brake clamps body in support of materials and processing method and so on is also in constant development, identify processing technology and clamping plan and design, attain thus to the automobile brake clamps body stents processing technology further deeper understanding; The main use of the software has Pro/e, ANSYS and CAPP. Pro/E so ftware using 3 d entity the exact modeling, intuitive parts to reproduce the parts, accurate experience design intention, for parts of the process arrangement after help. Pro/E Mechanica module and the software ANSYS software, finite element analysis, combining do analysis processing produces in the process of the maximum displacement and the maximum stress, and the cutting tool for cutting dosages of the size of the choice to provide reliable basis. This topic use CAPP software developed including making the process route and process design, the complete process documents and improve the process of standardization and standardization. Early detection and solve. According to the retrieval, this in processing industries, and no one made the corresponding introduction. Pro/E software can be accurately to establish various large and complex models. ANSYS software in products manufacturing advance found potential problems, but its modeling ability are weak. ntsThe two tools combined, foster strengths and circumvent weaknesses, give full play to the advantages of two kinds of software research and development, is the first choice of complex mechanical structure scheme. This is also I choose the two software reasons. Previous engineering personnel with Pro/E complete three dimensions solid parts design, then use to Mechanica parts structure finite element analysis to find the place, and weak structure is improved. And Im Pro/E, ANSYS will be applied to the design process of parts, make the past only in process actual implementation, can come into the open process defect, process design stage in can and The error after reflects the workpiece machining allowance method to calculate is, by definition, the processing, surface: its smallest machining allowance (Zbmin) are processing parts of two adjacent step freeways will limit of the difference of the minimum size; Its the biggest machining allowance (Zbmax) are processing parts of two adjacent step freeways will limit of the difference of the largest size. Inside surface processing, the minimum machining allowance is processed spares the maximum limit adjacent freeways will step size poor; Its the biggest machining allowance is processing components work of two adjacent step of the difference of the minimum size limit. The assistant time and basic time coincidence method, using the workbench processing center, get the staff in the cutting process completed work, and then, for auxiliary of the area is larger, and the volume of parts and relatively small, so can use one processing DuoGe parts to make the parts, the piece processing time as little as the basis, double the nc machining center area can also arranged four parts. The rotary worktable, two workpiece in processing at the same time, the clamping workpiece, the other two rotating, processing of just install two workpiece. Selection of cutting parameter and the formulation of &fair standards. Choose the right to improve the cutting dosages, cutting efficiency and guarantee the necessary tools durability and economy, ensure machining quality, has the vital role. Reasonable choice when processing cutting dosages should first choose a as far as possible big, secondly, optimizing the back of choice a larger feeding, and the last in the cutting tool durability, process system stiffness, machine tool power under the terms of the license, the rational choice of cutting speed. &fair standards also says time is fixed in a certain technology organization established under the condition of ntscomplete unit out products (such as a parts) or a job (such as a process that must be consumed time). &fair standards is not only, also be the measure index productivity arrange production plan, the calculations of the production cost is an important basis for new or expansion of the factory, is also (or workshop) computing devices and workers number of basis. Brake caliper disc brake the car body is the critical, brake movement is in the grips body on the final. Installed in clamp body on parts and 16 pieces. One of the more important parts: brake caliper piston, piston callipers at the stents, sealing ring, friction piece, brake caliper shaft pins, spring of and purge screw, etc. Studio, brake fluid through the clamp body JinYou mouth will be pressure to brake caliper Detroit, and by the brake friction pressure before the pistons will to block, press the brake disc, and make clamp body in the brake caliper shaft pins, driving the sliding friction, also after pressure brake disc brake, complete action. The car brake disc brake caliper body shape, structure, material complex special for QT450-10, hardness is HB143-217, machining allowance for 3 mm, form and position tolerances stricter requirements. This product is the important parts, and related to Chinas automobile brake disc importied problem. In the existing gm in machine tool is completed or processing difficult brake caliper body, especially the lumen of processing, tank must determine the process, to ensure the quality of the processing equipment. Because in general on the machine processing, so blank datum positioning to repeated use, the request to have the precise location of the datum plane, this and use machining center is a very big difference. Such as we are in the process of slot PNE480 CNC machine even with pure inside the car, to ensure that slot cavity type, detection is precision with anatomical projection and after adjustment method of projection. Were now being mass production craft ready to work, according to the auto industry high starting point, large quantities of specialization, the policy, we have identified on the domestic equipment, save funds, and choose the XK6040 CNC milling machine. nts 附 录 B 外文文献翻译 中国的工程师和用户还停留在前盘后鼓的理念上，而前、后盘式制动器的应用才是商用车提高制动性能的最佳方案。由于后鼓式制动器在温度升高后，制动性能衰减很大，导致前轴上盘式制动器承受不应承担的过多负载，致使盘式制动器的过载，制动片寿命的缩短。 因轿车在制动过程中，由于惯性的作用，前轮的负荷通常占汽车全部负荷的 70% 80%，所以前轮制动力要比后轮大。生产厂家为了节省成本，就采用了前轮盘式制动，后轮鼓式制动的混合匹配方式。采用前盘后鼓式混合制动器，这主要是出于成本上的考虑。随着我国国民经济的快速发展，普通消费者对汽车安 全和环保要求日益提高，微型汽车行业从微型货车起步，过渡到微型客车，再提升到使用微型轿车作为代步工具，成为历史发展的必然；另一方面，所有微型汽车企业已将主要资金和力量转向微型轿车行业，推出适应消费者不同需求的微型轿车产品，一些民营企业也将微型轿车作为进入汽车市场的突破口，不断的价格大战，使得微型轿车价格已不再 “ 曲高和寡 ” ，开始贴近普通百姓 。 nts盘式制动器主要有钳盘式和全盘式两种，现代汽车上应用最多的就是钳盘式制动器，它的旋转元件是制动盘，固定元件是制动钳。而根据制动钳的运动方式又可分为定钳盘式制动器、滑动钳盘式 制动器和钳盘式制动器，其中滑动钳盘式制动器应用更广。钳盘式制动器的工作原理就类似于自行车上的刹车，在制动过程中，制动钳将制动块挤压到制动盘上，随着制动盘和衬块之间的摩擦逐渐的将速度降下来。而滑动钳盘式制动器就是制动钳可以相对制动盘作轴向滑动；只在制动盘的内侧设置油缸，而外侧的制动块则附装在钳体上。盘式制动器在使用过程中，也会出现故障，其中比较常见的有气阻、制动力不足和制动时有噪声等 。 盘式制动器的发热部位集中在很窄的制动衬块上，其单位压力又比鼓式制动器大，制动衬块和钳体的活塞直接接触，因此制动时的热量极易传 给制动液。这样，使盘式制动器容易产生气阻现象。但是，若采取相应的措施，也可防止气阻现象的发生。 微型及普及型汽车在我国有很大市场， 近年来内需扩大带动了对微型汽车市场需求量的增加。有关部门认为中国经济已经进入适度增长的平台，这必将拉动汽车市场的稳定增长。去年，中国各企业效益好转，居民可支配收入增加，致使个人对汽车需求提高；国家实施西部大开发战略，对微车市场无疑也是巨大的潜在需求。 从 0.9L 到 1.6L，价格适合我国nts国情 ,适合正在发展的中国的现况。 汽车制动器钳体支架 是汽车重要零件之一，随着现在设计加工制造技术的发 展， 制动器钳体支架 的材料及加工手段等也在不断发展，确定加工工艺与装夹方案及设计，从而达到对汽车 制动器钳体支架 加工工艺进一步更深了解； 主要用到的软件有 Pro/ENGINEER、 ANSYS 和 CAPP。利用 Pro/E软件进行三维实体零件的精确建模 ,直观地再现了零件，准确体会设计意图，为零件以后的工艺安排提供帮助。 Pro/E软件的 Mechanica 模块和 ANSYS 软件结合起来做有限元分析 ,分析加工过程中产生的最大位移和最大应力 ,为切削用量和刀具尺寸的选择提供可靠的依据。本课题利用 CAPP 软件编制出包括制订工艺路线 和工序设计在内的完整工艺文件，提高了工艺的标准化和规范化。早发现并解决。根据查新检索，这在加工行业里，还没有人作过相应的介绍。 Pro/ E 软件可以精确地建立各种庞大复杂的模型。 ANSYS 软件在产品制造前预先发现潜在的问题，但它的建模能力比较弱。这 2 个工具结合起来 ,扬长避短 , 充分发挥 2 种软件的优势 ,是研究开发复杂机械结构的首选方案。这也是我选择这两个软件的原因。以往工程人员利用 Pro/E 完成三维实体零件设计，再运用 Mechanica 对零件结构进行有限元分析，找出结构薄弱
