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轴式弹性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。
In order to improve the lateral dynamic performance of 6-axis speed-raised locomotive with rigid overhead suspension system in our country, a modified scheme of using two rubber elements in elastic suspension at the motor end of the shaft is proposed, and two types of drive clearance clearance schemes are given . The multi-body dynamics software SIMPACK was used to set up a detailed kinematic model of 2C0-axis elastic frame-suspended vehicle. By comparing the rigid suspension of the three-axis bogie frame-end drive with two modifications of locomotive dynamic performance, Improve the locomotive’s horizontal running performance and large and medium radius curves through horizontal performance, enhance locomotive speed adaptation to the line and reduce its sensitivity to parameters, while the structure allows the conditions should be as large as possible to select a large drive Stop gap.
