空气制动预压力对全自动驾驶地铁列车精准停车影响的分析

Impact Analysis of Pneumatic Brake Pre-pressure on the Accurate Stop of Fully Automatically Driving Metro Trains

通过对全自动驾驶地铁列车电空制动混合的原理分析,结合既有项目的实际情况,对空气制动系统预压力值进行合理的设定,得出施加预压力与空气制动系统响应时间之间的匹配关系,为全自动驾驶地铁列车精准停车提供有力参考。

Based on the principle analysis of the electro-pneumatic braking hybrid of fully automatic driving subway trains,the pre-pressure value of the pneumatic braking system is reasonably set according to the actual situation of existing projects.The matching relationship between the applied pre-pressure and the response time of the pneumatic brake system is obtained,which provides a powerful reference for the accurate stop of fully automatic subway trains.
