抗蛇行减振器常见故障对高速列车动力学性能的影响
Influences of common faults of anti-yaw damper on dynamic performances of high-speed train
摘要
Abstract
Taking CRH380B as an instance,combined with common anti-yaw damper faults in practice,a vehicle dynamics model is established using SIMPACK simulation soft-ware based on vehicle dynamics theory,and research on vehicle dynamics is conducted by changing the damping characteristics of anti-yaw damper to simulate different types of faults.The results show that anti-yaw damper faults have great impacts on the riding quality,stability and curve negotiation performance of the vehicle when the residual damping force of anti-yaw damper is less than 50％ of the standard damping force after damper faults.The vertical and lateral riding indexes of the vehicle are 1.85 and 2.20 respectively,the derailment coefficient reaches 0.45,and the nonlinear critical velocity reduces to 271 km/h when the residual damping force is 50％ of the standard force.If anti-yaw damper has a character of unloading speed of 0.03 m/s and unloading force of 8～9 kN,the dynamic performance of the vehicle could reach a relative optimal state.关键词
