摘要
基于谐波函数方法来描述车轮多边形,建立地铁车辆动力学仿真模型;分析多边形幅值、阶次对不同速度等级下车辆的动力学性能影响;结合动力学指标着重探讨车轮出现跳轨之后的动力学表现。
The wheel polygon is described based on the harmonic function method,and the dynamic simulation model of the subway vehicle is established;the influence of the polygon amplitude and order on the dynamic performance of the vehicle at different speed levels is analyzed;combined with the dynamic index,dynamic performance is emphatically discussed after wheel jumps.
