摘要/Abstract

摘要： 车轮磨耗、过量镟修或钢轨过度打磨导致轮轨匹配等效锥度变化，时常诱发车辆一次蛇行和二次蛇行失稳现象，而传统被动抗蛇行减振器难以有效应对不同蛇行失稳类型。为此，提出一种基于液压橡胶节点的变刚度抗蛇行减振器，通过电磁比例阀动态调节减振器的串联刚度，并设计相应的控制策略。建立变刚度抗蛇行减振器及其液压橡胶节点的力学模型，通过试验验证液压橡胶节点的动态特性。基于减振器力学模型与控制策略，搭建车辆联合仿真模型，分析不同轮轨匹配关系下变刚度抗蛇行减振器对车辆蛇行失稳的抑制效果。结果表明，在一次蛇行失稳下，车体横向加速度振动主频处幅值降低78.9%；在二次蛇行失稳下，构架端部横向加速度振动主频处幅值降低79.7%。

Abstract: Wheel wear, excessive wheel truing, or excessive rail grinding can lead to changes in the equivalent conicity of wheel-rail matching, which in turn trigger primary and secondary hunting instability phenomena in vehicles. Traditional yaw dampers are difficult to effectively cope with different types of hunting. To address this, a variable stiffness yaw damper based on a hydraulic rubber joint is proposed. The series stiffness of the damper is dynamically adjusted through an electromagnetic proportional valve, and a corresponding control strategy is designed. A mechanical model of the variable stiffness yaw damper and its hydraulic rubber joint is established, and the dynamic characteristics of the hydraulic rubber joint are verified through experiments. Based on the damper's mechanical model and control strategy, a vehicle co-simulation model is built to analyze the suppression effect of the variable stiffness yaw damper on vehicle hunting motion under different wheel-rail matching conditions. The results show that under primary hunting conditions, the amplitude at the main frequency of the lateral acceleration vibration of the carbody is reduced by 78.9%; under secondary hunting conditions, the amplitude at the main frequency of the lateral acceleration vibration at the end of the bogie is reduced by 79.7%.
