城市轨道交通车辆打滑对信号系统的影响

Impact of Train Slips on Urban Rail Transit Signaling System

城市轨道交通车辆打滑会造成列车紧急制动次数的增多和紧急制动距离的延长,从而造成一定的安全风险。通过对具体案例的分析,阐述了因雨天使轮轨黏着系数下降所造成的车辆打滑对信号系统的影响,并给出了相应的预防控制措施。

Urban rail transit train slip will cause more emergency braking and extension of emergency braking distance,which brings safety risks for operation. Through concrete case study,the impact of train slip on the signal system caused by the decrease of wheel rail adhesion coefficient in rainy days is described,the preventive measures are put forward.
