摘　　要：为研究抗蛇行减振器失效对车辆运行平稳性的影响,选择尚未投入运营的地铁车辆,通过拆除抗蛇行减振器的方式模拟其故障工况,对拆除抗蛇行减振器前后车辆的运行平稳性和振动特性进行线路试验研究。试验结果表明:拆除抗蛇行减振器对车辆运行平稳性有显著的影响,对于横向平稳性尤其明显。拆除的抗蛇行减振器越多,运行平稳性指标越大。抗蛇行减振器失效对车辆高速运行时以及通过直线或者大半径曲线时的平稳性影响较大。This article chooses a metro yet for operation to investigate the effect of yaw damper failure on the ride quality of the metro.By removing the yaw damper to simulate its fault condition,the running stability and vibration characteristics of the vehicle before and after the removal of the yaw damper is studied.The experimental results show that the removal of the yaw damper has a significant impact on the ride quality of metro,especially on lateral stability.The more yaw dampers are removed,the more significant the increase in the stability indicators of vehicle operation.The failure of the yaw damper has a greater impact on the stability of the vehicle when it is running at high speed or passing through a straight line or a large radius curve.
