摘　　要：为了研究车轮不对称磨耗对地铁车辆动力学性能的影响,根据实测地铁车轮型面数据的不对称磨耗现象,设置了车轮同相不对称磨耗、反相不对称磨耗、前后不对称磨耗和初始型面4种工况.运用多体动力学软件SIMPACK建立车辆系统动力学模型,分析比较4种工况对车辆动力学性能指标的影响.结果表明:同相不对称磨耗的车辆安全性能最差,其次是反相不对称磨耗,前后不对称磨耗工况的表现较好,对车辆的安全运行和车轮的维护和镟修具有一定的指导意义.In order to study the influence of wheel asymmetric wear on the dynamic performance of metro vehicles,the four working conditions of wheel in-phase asymmetric wear,reverse asymmetric wear,front and rear asymmetric wear and initial profile are sets up according to the asymmetric wear phenomenon of measured wheel profile data of metro vehicles.The dynamic model of vehicle system is established by using SIMPACK,and the influence of the four working conditions on vehicle dynamic performance is analyzed and compared.The results show that the safety performance of vehicle with in-phase asymmetric wear is the worst,followed by reverse asymmetric wear,and the performance of the front and rear asymmetric wear conditions is better,which has certain guiding significance for the safe operation of vehicles and the maintenance of wheels.
