摘　　要：车辆一次蛇行稳定性对车辆运行平稳性及乘坐舒适性等有重要影响。在分析轨道车辆一次蛇行运动失稳机理的基础上,利用SIMPACK建立CRH3型高速列车多刚体整车系统仿真模型,仿真计算不同等效锥度下不同一系横向定位刚度K_(Py)和一系纵向定位刚度K_(Px)转向架蛇行运动频率,得到不同等效锥度下提高车辆一次蛇行运动稳定性的一系定位刚度范围。The stability of primary hunting motion of the vehicle has an important influence on the running stability and riding comfort of the vehicle.Based on the analysis of the mechanism of the instability of primary hunting of rail vehicles,SIMPACK is used to establish a simulation model of the multi-rigid body system of the CRH3 high-speed train,the frequency of bogie with different lateral primary suspension positioning stiffness K_(Py)and longitudinal primary suspension positioning stiffness K_(Px)under different equivalent tapers are simulated and calculated to abtain a series of primary suspension positioning stiffness that can improve the stability of primary hunting under different equivalent tapers.
