摘要
针对地铁车辆车轮踏面发生的沟槽状磨耗现象,利用车辆动力学仿真软件SIMPACK建立了标准踏面和实测沟槽磨耗踏面情况下的地铁车辆动力学分析模型,并对车辆动力学性能进行了对比。仿真结果表明,车辆在标准踏面和沟槽磨耗踏面情况下的动力学性能考察指标在数值上相差不大。
In view of the tread hollow appeared in metro wheels,the dynamics analysis model of metro vehicles under conditions of standard tread and actually measured tread with tread hollow is established with the vehicle dynamics simulation software SIMPACK.And the dynamics performances of vehicles are compared.The simulation result shows that there is no obvious difference in value between the dynamics performance indexes of the standard tread wheels and the tread hollow wheels.
