摘　　要：通过试验方法对我国高速列车用抗蛇行减振器特性进行了研究,分析其动态阻尼及动态刚度参数变化情况,在一定的幅值下,抗蛇行减振器动态刚度随着频率值增加而增加,而动态阻尼值随频率增大而减小。同时利用动力学仿真软件SIMPACK对高速列车进行了适应性分析,包括平稳性、车体最大横向加速度以及脱轨系数计算。仿真结果表明:抗蛇行减振器可以兼顾直线稳定性和曲线通过性能,验证了抗蛇行减振器在高速列车实际运用中的优越性和必要性。The characteristics of the anti-yaw damper for high-speed trains in China were studied by means of the test method, including the analysis of dynamic damping and dynamic stiffness parameters. The experimental results showed that the dynamic stiffness of the anti-yaw damper increased with the increase of the frequency value, while the dynamic damping value decreased. At the same time, the adaptability analysis of the high-speed trains, including the stability, the maximum lateral acceleration of the vehicle body and the derailment coefficient, were calculated by using the dynamic simulation software SIMPACK. The simulation results showed that the anti-yaw damper meanwhile ensures the linear stability and the curve through performance, which verified the superiority and necessity of the anti-yaw damper in the practical application of the high-speed trains.
