摘　　要：利用SIMPACK软件建立高速动车模型,通过改变轮对初始偏转角来模拟轮对安装误差以及运用过程中一系橡胶定位装置出现的纵向定位误差,讨论了这些误差对车辆直线动力学性能的影响。结果表明,一系定位纵向误差使得车轴偏转对车辆横向动力学性能的影响较大。The SIMPACK software is used to establish the model of high speed motor car.Via changing the initial reflection angle of wheelsets,the wheelset installation error as well as the longitudinal positioning error appeared in the primary rubber positioning device in operation is simulated.The effect of these errors on the linear dynamics performance of vehicles is discussed.The result shows that the axle reflection due to the longitudinal error in the primary positioning affects the lateral dynamics performance of vehicles greatly.
