内容简介：

I摘 要国内汽车市场迅速发展，随着汽车保有量的增加，带来的安全问题也越来越引起人们的注意，由于汽车零部件引发的事故层出不穷。所以汽车零部件质量测试越来越受人们的重视。零部件特别是电器部件更是引起注意，电器测试系统的研究正朝向小型轻量化、设计制造信息化和性能检测自动化方向发展。本设计是针对教学中起动机、发电机的测试实验台进行研究设计。设计出具有测试功能的实验台，能够简单便捷的检测出零件的性能状况。同时能够达到教学施教的效果。设计中主要采用转矩传感器测试起动机的起动转矩和全制动转矩，运用调速电动机皮带传动，控制发电机的转速观察发电机的电压变化。通过这些设备的连接电路进行测试，得出数据结论。并作出分析处理，测试出的数据与额定数据进行比较计算，得出起动机、发电机的工况。关键字：实验台；设计；测试；特性分析；转矩IIABSTRACTThe rapid development of the domestic auto market, with the increase in cars, security issues brought about by more and more attention, as a result of car accidents caused by any components. Therefore, the quality testing of automotive components increased attention. Electrical parts and components in particular is attracting the attention of components, electrical testing systems is towards a small light weight, design and manufacture of information technology and performance test automation direction.The design is aimed at teaching starters, generators, test-bed for the test study design. Designed with the test-bed testing, simple and convenient to detect the status of performance parts. Teaching at the same time to achieve the effect of teaching. The design of the main torque sensor used to test the starting torque starter and full braking torque, the use of a belt drive motor, control the speed of generator voltage generator changes observed. Through these devices to connect the circuit test data to draw conclusions. And analyzed the IIIprocessing, testing of the data and rating data calculated starters, generators working conditio
