摘要
简单分析了轮轨间的粘着特性,对机车上IGBT变流器供电的异步牵引电机的转矩脉动进行了理论和仿真计算,根据计算的结果讨论了牵引电机转矩脉动对机车粘着利用的影响,并对机车运行时最佳蠕滑速度点的选取提出了建议。
The adhesion characteristic between wheel and rail is analyzed. The torque fluctuation of the AC traction motor feed by IGBT converter is calculated and simulated, and the effect on adhesion utilization is discussed according to the calculation and simulation, some advice on how to define the optimal creep velocity is presented.
