摘　　要：针对某型高速动车组运营时存在车辆横向晃动的现象,基于实测线路钢轨廓形对车轮踏面外形进行了局部优化,并进行了仿真计算和线路试验。结果表明优化方案可有效抑制横向晃动,改善车辆的横向平稳性。In view of swaying of vehicles in operation of a certain type of high speed multiple units, the local optimization for the contour of wheel tread is made on the basis of actually measured rail profile, the simulation calculation and on-track testing are carried out. The result shows that the optimization scheme can effectively control swaying and improve the lateral stability of vehicles.

关 键 词：动车组 车辆横向晃动 踏面优化 线路适应性
