摘要:

为得到油压减振器特性参数对高速动车组临界速度和轮轨磨耗的影响,以CRH380B型动车组为实例,基于车辆动力学理论,采用动力学仿真软件SIMPACK建立动力学模型,对二系横向减振器、抗蛇行减振器的橡胶节点刚度和阻尼特性进行研究。结果表明:抗蛇行减振器橡胶节点刚度最优值在10~12 MN/m范围内,当节点刚度小于此范围时,临界速度显著下降,轮轨磨耗功率缓慢增加;节点刚度大于此范围时,临界速度缓慢下降,但磨耗功率急剧增加。二系横向减振器橡胶节点刚度对临界速度和轮轨磨耗的影响较小,其最优取值为4.25 MN/m。抗蛇行减振器和二系横向减振器阻尼特性对临界速度和轮轨磨耗均有一定影响。

Abstract:

In order to obtain the influence of hydraulic shock absorber characteristic parameters on the critical speed and wheel-rail wear of high-speed train, take CRH380B as an example, a vehicle dynamics model is established using SIMPACK soft-ware based on the vehicle dynamics theory.Select the rubber joint stiffness, damping characteristics of secondary lateral shock absorber and yaw shock absorber to research. The results showed that: rubber joint stiffness of yaw shock absorber optimal ranges is 10-12 MN/m. When the stiffness is less than this value, the critical speed decreased significantly, the wheel-rail wear slowly increase. When stiffness is greater than this value, the critical speed slow down, but a sharp increase in wheel-rail wear. rubber joint stiffness of secondary lateral shock absorber have little effect on the critical speed and wheel-rail wear, optimal value is 4.25 MN/m. The damping characteristics of yaw shock absorber and secondary lateral shock absorber have some influence on the critical speed and wheel-rail wear.

Key words: critical speed, high-speed trains, wheel-rail wear, characteristic parameters of hydraulic shock absorber
