宁波轨道交通5号线一期列车打滑故障分析OA

Targeting at the train wheel slide failure on the transfer track of Phase Ⅰ of Ningbo Rail Transit Line 5,which prevents the trains from running in the fully automatic train operating mode,this study conducts a field survey on the track status,analyzes the main reasons leading to the train wheel slide,and introduces the speed measurement equipment of signaling system,the judgment logic of the wheel slide and the protection strategy.Based on the failure data,it examines how to reduce the operational impacts of the train wheel slide,and how to prevent the trains from entering the state of repeated wheel slide by optimizing the wheel slide judgement conditions and speed measurement principles,thereby improving the reliability of speed and distance measurement.
