摘　　要：车辆蛇行运动稳定性是车辆动力学性能的重要内容。为了探讨货车转向架承载鞍横向加速度与车辆运行稳定性的关系,应用SIMPACK动力学性能仿真软件建立了某货车的动力学仿真模型,在随机载荷条件下进行仿真分析,并与UIC标准、AAR标准进行分析比较。结果表明,承载鞍横向振动加速度可以作为评判货车蛇行运动稳定性的参考指标。Vehicle hunting stability is an important content of vehicle dynamic performance .In order to find out the relationship be-tween the lateral acceleration of wagon bogie adapter and vehicle running stability ,the paper establishes the dynamic simulation mod-el of a wagon by dynamic performance simulation software SIMPACK and conducts the simulation analysis while the wagon is under random load .Through comparing the simulated data with UIC standard and AAR standard ,the result shows that adapter’s lateral vibration acceleration can be used as reference index of wagon hunting stability .
