中文摘要：
为了开发我国200km／h速度等级的C0-C0轴式六轴机车新型转向架，本文采用多刚体动力学软件SIM-PACK建立了详细的C0-C0轴式机车动力学模型，比较了电机采用顺置和一、二与五、六位电机对置布置时，驱动装置刚性和弹性悬挂条件下，机车的稳定性、直线运行性能和曲线通过性能，指出：采用电机对置，可以提高机车的稳定性，降低直线和大半径曲线运行的轮轨横向力；采用驱动装置弹性架悬结构，更有利于提高机车稳定性和减小轮轨横向力，减弱机车对线路条件的敏感性，尤其是改善机车运行速度超过140km／h后的横向动力学性能。采用电机对置和驱动装置弹性悬挂结构的C0-C0轴式机车可以满足200km／h速度的运行要求，是新型转向架的最优设计方案。
英文摘要：
A detailed model of a locomotive of six axles （i. e. , C0-C0） is established by SIMPACK to develop new bogies for the 200 km/h locomotive. Comparisons are made with regard to the stability and running performances on tangent or curved tracks of the locomotive with the rigid or flexible driving equipment suspensions and ＂face to back＂ or ＂back to back＂ setting of motors. The stability can be increased and the wheel-rail lateral forces can be reduced on tangent and large-radius curved tracks by ＂back to back＂ setting of motors. Using flexible driving equipment suspensions, namely, suspending driving motors in the bogie frames with rods, is beneficial to the running stability, decrease of the lateral wheel-rail forces, weakening of the sensitivity the locomotives to track conditions, and especially to the lateral dynamic riding qualities when the locomotive runs at speeds above 140 km/h. The locomotive with C0-C0 axles can meet the running need at 200 km/h by ＂back to back＂ setting of motors with flexible driving equipment suspensions. It is the optimal alternative for design of the new-type bogies.
