摘要
自动驾驶模式下城轨列车停车时的冲欠标问题一直困扰着很多城轨交通用户，为提高系列化标准地铁列车自动驾驶模式下的停车精度，从影响车辆制动性能的电制动力、电空配合、空气制动预压力控制、空气制动力、闸瓦、闸片以及轮轨黏着等方面进行分析，结合既有线路列车实际运营测量数据，验证电制动力发挥精度、电空配合参数、空气预压力大小、闸瓦闸片摩擦因数与表面状态以及轮轨表面状态都会不同程度地影响列车停车精度，通过试验调试与线路验证，给出提高系列化标准地铁列车自动停车精度的制动性能优化建议。
Abstract
The problem of exceeding or short of standard line under ATO mode of metro train has always troubled many urban rail transit users
in order to improve the parking accuracy of series standard metro trains under ATO mode
the electric braking force
electric air coordination
air braking preload control
air braking force
brake shoe
brake pad and wheel rail adhesion that affect the vehicle braking performance were analyzed. Combined with the actual operation measurement data of existing trains
it was verified that the exertion accuracy of electric braking force
electric air coordination parameters
air preload
brake shoe
brake pad friction coefficient and surface state
as well as wheel rail surface state will affect the train parking accuracy to varying degrees. Through test debugging and line verification
the braking performance optimization suggestions to improve the automatic parking accuracy of serial standard metro trains were given.
