Research on Dynamics of the Vehicle-Track Vertical Coupling System with Resilient Wheelsets

建立了弹性轮对车辆 -轨道垂向耦合系统动力学模型 ,推导了弹性轮对车辆 -轨道垂向耦合系统振动微分方程。通过输入脉冲型激扰 ,对弹性轮对车辆 -轨道垂向耦合系统进行了轮轨力及轮轨接触应力的动力学仿真 。

The dynamic model of the vehicle track vertical coupling system with resilient wheelsets is set up. The differential equations of the coupling system are derived. By inputting impulse excitation, the dynamic simulation of wheel/rail contact stress for resilient wheelset systems is carried out and the results are analyzed and compared with the system of rigid wheelset.
