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。
A simplified model of anti-snake shock absorber, Maxwell model, is introduced. A high-speed EMU trailer model is established by using SIMPACK software. Based on the nonlinear stability and linear stability analysis, the influences of different series of longitudinal positioning stiffness and equivalent taper Influence of Series Stiffness of Anti - snake Shock Absorber on Critical Speed. The results show that, with a series of longitudinal positioning stiffness and equivalent taper to match the anti-snake shock absorber series stiffness on the stability of the vehicle system is different, with a series of longitudinal positioning stiffness and equivalent taper Anti-snake shock absorber series stiffness have different optimal values.
