附 录 A 外文文献 Brake testing equipment functions and operations ABSTRACT Flat-plate brake testing units, is by far the best most most popular brake testing equipment. Bench work surface for the correction system a real sense of the platform. It can provide accurate positioning for the car. Clamping system, drawing system, measuring system, repair of vehicles and platforms are composed of an organic whole. And can be attached devices such as the second lift. This form of correction system with its comprehensive features are becoming standard calibration system. Currently, flat on the market is rich brake testing equipment, imported products such as Karl Rahner have Car-O-Iiner, CAR-BENCH to force too, and Shibinnisi brands, general science and technology was relatively advanced, but easy to use price higher than domestic equipment, special maintenance station and the general strength of the manufacturers will choose this high-end equipment. And like the Pentium, excellence, Legacy, and domestic equipment such as special kind of after-sales service, reliable, relatively low price, is the product of choice and medium-sized testing station. INTRODUCTION A) We have to understand automotive braking system of detection of structural feature. Car brake testing system is used in experimental research and development of new cars, new car delivery inspection and road traffic management department of the regular inspection of the vehicle braking system performance evaluation parameters for quantitative detection and diagnosis of test equipment. B) The brake testing units on the market for a variety of styles, the more prominent are two types: roller peace panel. Whatever the style must have the following in common: 1. With high-intensity fixtures； 2. With more sensors； 3. Capable of more, a full range of inspection work； 4. Capable of accurate measurement and accurate detection of braking performance is good or bad. Flat-plate brake test bench equipment to solve the shortcomings of drum. Flat out not only to test the cars maximum braking force at each wheel, blocking force and axle load, but also provide the braking force, axle load in the testing process over time curve. Drum-type detection units to overcome the inherent deficiencies. The inspection system speed, high precision, the results intuitive, and easy to install and move, low energy consumption (due to no need to install the motor, power roller is only 1 / 100), small footprint, simple operation and maintenance and so on. C) regardless of the equipment, its operation can be divided into the following four steps: 1. On the train: for inspection of vehicles driving on the test stand by hand. 2. Axle load measurement: measuring axle load is a subsidiary of braking performance test equipment items, as long as the stage set of four axle braking sensors to measure the axle load of vehicles tested, while the axle is the braking force further analysis based on the credibility of test results, it is essential. 3. Step on the brake pedal: all four wheels until the vehicle brake on the board, depresses the brake pedal, the braking force measurement. 4. Braking force measurement. Measurement of braking performance braking force is the most important testing equipment testing, mainly through the braking force sensor to measure, braking force sensors are generally installed on the test board below. Through the above four steps, the vehicle braking performance test has basically completed the work. In short, the advent of brake testing equipment, reduce labor intensity of the test staff, improve efficiency, making the car testing industry embarked on the standardization and modernization of the road. D) The brake testing solution for classification and their characteristics Automobile Brake Tester is a performance cars brake testing equipment, testing the main parameters include: the braking force, braking force balance, wheel blocking force, braking coordination time. According to the test works differently, brake inspection station can be divided into anti-and inertial forces； supported by the examination sets the wheels in different forms, automobile brake drum inspection station can be divided into the peace panel； by testing different parameters, brake inspection Taiwan can be divided into the braking force measurement type, the measured braking distance and overall parameters of three kinds； the number of axles detected by the examination table can be divided into single-axis type, two-axis and multi-axis categories. At present, widely used in automobile brake drum-type reaction plate brake test station test platform of peace. 1. Road test: the flat by the driver to accelerate to a certain speed on the road when the emergency brake pedal, by observing the imprint on the road and braking distance and the experience of their own experience to determine whether the normal vehicle braking performance. 2. Roller brake tester: the measured vehicle wheel sticky sand to release the two pairs of rollers, the drag roller by the motor, when the drum line speed up to 2 km / h - 5 km / h when the brake pedal, through the installed in the drum side of the force torque sensor size. This detection method requires a vehicle detection were measured before and after the axis of the brake, does not reflect the dynamic brake front and rear axles when the load changes, can not measure the braking vehicle braking coordination of time, can not fully reflect the braking energy, and the braking effect of other factors, such as leaf spring suspension or the rigidity of the braking performance. This detection method is a static test. 3. Flat-plate brake tester: road conditions simulated by the four steel plate sticky sand arranged in a certain way to ensure that a vehicle driving wheels when braking plate at 4, car to 5 km / h for a 10 km / h speed onto plate brake tester. When the emergency brake pedal, through the plate under the dozens of sensors and computer control systems to measure vehicle braking performance of the braking, suspension performance, leaf spring stiffness (carts) and other indicators, and can measure test speed value. CONCLUSIONS Automotive technology, automotive testing technology to promote the development of the automobile industry, a higher test requirements. Brake testing is far from easy work of braking distance measurements, more than the traditional testing equipment can achieve. It requires a scientific measurement of vehicle braking and find the problem. To achieve this function, is inseparable from the body correction system. Accessibility is also an increase in the development of brake testing equipment is a major trend. The design of more clever, more sophisticated technology, increased use of test panels sliding more and more. Equipment more and more complete. In short, the development of brake testing equipment is moving in automation, digital and multi-functional direction. 附 录 B外文文献的中文译文 制动检测设备的功能与操作 一、摘要： 平板式制动检测台，是迄今为止最为优秀的也是最流行的制动检测设备。台架式校正系统的工作台面为一个真正意义上的平台它可以为汽车提供精确的定位。夹紧系统、拉伸系统、测量系统、被修车辆与平台组成一个有机整体并可附挂二次举升等装 置。这种形式的校正系统以其完备的功能正成为校正系统的标准配置。 目前，市场上的平板式制动检测设备比较丰富，进口产品像卡尔拉得Car-O-Iiner, CAR-BENCH 使力得和史宾尼斯等品牌，一般科技含量相对先进、使用方便但是价格也比国产设备要高，一般特约维修站和实力雄厚的厂家会选择这种高端设备。而像奔腾、卓越、力狮和特样等国产设备售后服务可靠、相对价格偏低，是大中型检测站的首选产品。 二、介绍 一） 我们要了解汽车制动系统检测及其构造特征。 汽车制动检测系统就是应用于新车研究开发的实验、新车的出厂检验和交 通管理部门对上路车辆定期检验的对制动系统的性能评价参数进行定量检测诊断的试验装置。 二） 市场上的制动检测台为各种款式， 较为突出的分为两种：滚筒式和平板式。 无论何种款式都必须具备以下共同点： 1. 具有高强度的固定装置； 2. 具有较多的传感器； 3. 能进行多点、全方位的检测工作； 4. 能够进行精确的测量，准确检测出制动性能的好坏。 平板式制动检测试验台就解决了滚筒式设备的缺点。平板式不仅能测试出汽车每个车轮的最大制动力、阻滞力及轴重，还能提供制动力、轴重在检测过程中随时间变化的曲线。克服了滚筒式检 测台本身固有的不足。该检测系统测试速度快、精度高、结果直观，并有安装和移动方便、耗能少 (因不需安装电机，耗电仅为滚筒式的 1/100)、占地面积小、操作维护简单等优点。 三 ) 不论何种设备，其操作大体分为以下四步： 1. 上车：待检车辆通过专人驾驶上试验台。 2. 轴重测量：测量轴重是制动性能检测设备的附属项目，只要在制动台上设置四个轴重传感器即可测量待测车辆的轴重，而轴重又是进一步分析制动力检测结果是否可信的依据，因此必不可少。 3. 踩制动踏板：待到车辆四个车轮都在制动板上时，踩下制动踏板 ,测量制动力。 4. 制动力测量。测量制动力是车辆制动性能检测设备检测的重中之重，主要通过制动力传感器来测量，制动力传感器一般安装在测试板下面。 通过以上四步骤，车辆制动性能检测工作基本完成了。 总之，制动检测设备的问世，减轻了测试人员的劳动强度，提高了工作效率，使汽车检测业走上了规范化、现代化的道路。 四 )制动检测方案的分类与各自特点
