中文摘要：
为了改善我国现有驱动装置刚性架悬方式的六轴提速机车横向动力学性能，提出了在端轴电机端采用2个橡胶元件弹性悬挂的改造方案，给出了2种驱动装置止挡间隙方案。采用多刚体动力学软件SIMPACK建立了详细的2C0轴式律陛架悬机车动力学模型，通过比较三轴转向架端轴驱动装置刚性悬挂与2种改造方案的机车动力学性能。说明改造方案可以显著改善机车的直线运行横向性能和大、中半径曲线通过横向性能，增强机车提速后对线路的适应性，降低其对参数的敏感性，同时在结构允许的条件下应当尽可能选取大的驱动装置止挡间隙。
英文摘要：
To improve the lateral dynamic performance of the speed-raising six-axle locomotive with rigid axle-hung drive, it is proposed the improvement scheme to use 2 elastameric rubber parts as flexible suspension in the axle motor terminal. Two damper gap schemes are given for the drive. The detailed dynamic model with 2 CO axle flexible suspension is built by use of multi-rigid dynamic software SIMPACK. Through the comparison of the locomotive dynamic performances between the rigid suspension of terminal-axle drive for 3 axle bogie and the 2 reconstructed schemes, it is pointed out that the reconsauction schemes could improve dramatically the horizontal performance in linear running, and that in big and mid radius curve negotiation. Also improved is the adaptability to the lines after locomotive speed-up as well as the sensibility against parameters. Biggest possible damper gaps of the drive should be selected if the structure allows.
