摘要

介绍了抗蛇行减振器的简化模型——Maxwell 模型，采用SIMPACK 软件建立某高速动车组拖车模型，基于非线性稳定性和线性稳定性分析，研究了不同一系纵向定位刚度和等效锥度下抗蛇行减振器串联刚度对临界速度的影响。研究结果表明，与不同的一系纵向定位刚度和等效锥度相匹配，抗蛇行减振器串联刚度对车辆系统稳定性的影响是有差异的，在不同一系纵向定位刚度和等效锥度下抗蛇行减振器串联刚度有不同的最佳值。

Abstract

The Maxwell model, which was the simplified model of anti-yaw damper, was introduced. High-speed EMUs model wasestablished by using SIMPACK. Based on nonlinear and linear stability analysis, the influence of anti-yaw damper series stiffness withdifferent primary longitudinal stiffness and equivalent conicity on critical speed was studied. It showed that the influence of anti-yawdamper series stiffness with different primary longitudinal stiffness on critical speed was different. The anti-yaw damper series stiffnesswith different primary longitudinal stiffness and equivalent conicity had different optimal value.
