本文介绍了机车牵引控制器在不同运行条件下对轨道磨耗的性能。特别是，机车的动态响应变化的轮轨摩擦条件下进行的调查，目的是确定控制器设置对轨道磨损的影响。仿真结果表明，适当设计的蠕滑阈值、控制器和设置可以有效地保持较高的牵引力，同时避免钢轨磨损，特别是在低速加速过程中。
This paper presents the locomotive traction controller performance with respect to the track wear under different operation conditions. In particular, an investigation into the dynamic response of a locomotive under changing wheel–rail friction conditions is performed with an aim to determine the effect of controller setting on track wear. Simulation using a full-scale longitudinal–vertical locomotive dynamic model shows that the appropriately designed creep threshold, controller, settings can effectively maintain a high tractive effort while avoiding excessive rail damage due to wear, especially during acceleration under low speed.
