微机控制直通电空制动系统用阀试验研究

A Test of Valves in Micro-computer Controlled Braking System

介绍了微机控制直通电空制动系统用阀的功能、工作原理及其主要性能指标。结合试验台的测试,阐述了试验台的设计和阀的性能试验方法。对回差与输入上升下降速度、开启时间与充气速度、双向阀换向试验、试验时间控制、泄漏量试验与检测时间的选择等试验结果及其影响因素进行了分析。

This paper first introduces the functions and the working principle of the valves used in micro-computer controlled straight electro-pneumatic braking system, and indicates their main performance index. With a test on the testing platform, this paper discusses the design of the testing platform and the methods for the valves＇ test, analyzes the test results and the influencing factors, such as the time control, the leakage and the selection of testing time.
