北京地铁亦庄线车辆异常振动研究

Research on the Abnormal Vibration of Vehicles on Yizhuang Line of Beijing Metro

针对北京地铁亦庄线部分动车地板面出现的异常振动现象,进行了线路测试和数据分析,并通过对联轴节高度差的控制有效地解决了异常振动问题。

In view of the abnormal vibration appeared in the floor of some motor cars on Yizhuang Line of Beijing Metro,the measurement on track and analysis of data are carried out,and the problem of abnormal vibration is solved effectively through control of the height difference of couplings.
