The Study on Relationship between Motor Lateral Damper and Vehicle Dynamic Performance of Train base on SIMPACK

基于SIMPACK建立了我国某高速动车组动力学模型,仿真分析了电机横向减振器对车辆动力学性能影响,对减振器设计具有帮助作用。仿真结果表明:该高速动车车辆临界速度随着电机横向减振器阻尼系数增加呈先增加后减小趋势;车辆横向平稳性指标及乘坐舒适性指标随着电机横向减振器阻尼系数增加呈先减小后增加趋势,其阻尼系数对车辆垂向平稳性影响不明显;车辆安全性指标均随着阻尼系数增加呈先减小后增加趋势。

It is analyzed that motor lateral damper influence on vehicle dynamic performance through building the dynamic model of high speed vehicle based on SIMPACK.It may help the design and optimization of damper.Therefore,there is some of engineering application value.It could be concluded that critical speed increases firstly and then decreases with the augment of damping coefficient of motor lateral damper.Vehicle lateral stability index and ride comfort index decrease firstly and then increase with the augment of damping coefficient of motor lateral damper.And its damping coefficient has less effect on vehicle vertical stability.Vehicle safety indexes also decrease firstly and then increase with the augment of damping coefficient of motor lateral damper.
