摘要:为研究扭转刚度和扭转阻尼(即车轮的转向刚度和转向阻尼)对受横移控制的虚拟轨道车辆动力学性能的影响,采用多体系统动力学理论及控制理论,建立了考虑胎地耦合与机电耦合的虚拟轨道车辆动力学联合仿真模型。利用该模型,分析了车轮与转向架之间扭转刚度与扭转阻尼对车辆动力学性能和控制系统的影响规律。研究结果表明:扭转刚度和扭转阻尼确有必要存在且满足模型控制系统动态性能和动力学性能的扭转刚度选择2 kN/rad,扭转阻尼选择2 kN•s/rad。

Abstract:In order to study the effect of torsional stiffness and torsional damping(steering stiffness and steering damping of the wheel)on the dynamic performance and control system of virtual rail trains, a dynamic model of virtual rail vehicles considering tire-ground coupling and electromechanical coupling is established by using multi-body system dynamics theory and control theory. Using this model, the influence of the torsional stiffness and the torsional damping between wheel and bogie on vehicle dynamic performance and control system is analyzed. The results show that the model meets the standards of the control system and the dynamic performance when the torsional stiffness and the torsional damping are 2 kN/rad and 2 kN•s/rad.
