某地铁列车ATO模式启动冲击超限故障分析与解决

Analysis and Solution of a ATO Subway Train Starting Overshoot Fault

针对某城市地铁车辆在正式运营期间,ATO模式下列车启动冲击较大的问题,分析现场故障数据,定位故障系统,并通过搭建半实物仿真平台进行反复模拟和测试,最终确定故障原因,并提出解决方案,整改后故障得以完全消除。

Aimed at the problem of high impulse when train starts up under ATO mode during the formal operation of a metro vehicle,this paper analyzes the field fault data,locates the fault system,and through building a hardware-in-the-loop simulation platform for repeated simulation and testing,finally determines the fault causes,and puts forward solutions,which can completely eliminate the fault after rectification.
