CRH_3动车组横向加速度超限报警与轮对踏面外形尺寸的相关性分析研究

Analysis and Research of the Correlation Between the Alarm Due to the Overrun of the Lateral Acceleration and the Shape of Wheel Tread for CRH_3 EMU

通过长期跟踪测量武广线上横向加速度超限(173D/173E)报警故障的CRH_3动车组的轮对踏面外形尺寸,着重分析了横向加速度超限报警故障与S1002CN踏面外形各尺寸参数变化的相关性,提出了基于合理控制横向加速度超限报警故障的轮对旋修建议。

In this article, through long-term follow-up measurement of the parameters of wheel tread for CRH3 EMU which has the a- larm problem resulted in the overrun of the lateral acceleration and was operating in Wuhan Guangzhou line. Analysing emphatically the correlation between the alarm due to the overrun of the lateral acceleration and the change of the parameter of the S1002CN wheel tread. Offering a proposal on wheelset lathing based on reasonable control the problem of the overrun of lateral acceleration.
