中间轴驱动装置固定对弹性悬挂式机车动力学性能的影响

Impact of locomotives with flexible drive dynamics performance by the middle-axis driving equipments fixed on bogie frame

为防止弹性悬挂式机车中间轴驱动装置横向位移过大,发生碰撞,提出了端轴驱动装置弹性悬挂、中间轴驱动装置固定连接的方式。利用多体动力学软件SIMPACK建立整车动力学模型,对比分析驱动装置悬挂方式对机车动力学性能的影响,认为采用这种悬挂方式是合理可行的。

This paper advances end-axis driving equipments flexible on bogie frame and middle-axis driving equipments fixed on it, to avoid the collision caused by the middle-axis driving equipments over-displacement to the locomotives with flexible drive. A whole dynamics model by SIMPACK is established to analyze the locomotive dynamics performance impact by comparing the different driving equipment suspension mode. It is considered that this mode is feasible.
