Tread wear and rolling contact fatigue (RCF) damage propagated on railway wheels are the two extremely important focal points as they can tremendously deteriorate wheel/rail interactions and hunting stability and destroy wheel surface materials, and subsequently, cut down the lifetime of the wheels. The on-board anti-slip controllers are of essence aiming to hold back the striking slipping of the powered wheelsets under low-adhesion wheel/rail conditions. This paper intends to investigate the impact of anti-slip control on wheel tread wear and fatigue damage under diverse wheel/rail friction conditions. To this end, a prediction model for wheel wear and fatigue damage evolution on account of a comprehensive vehicle-track interaction model is extended, where the wheel/rail non-Hertzian contact algorithm is used. Furthermore, the effect of frictional wear on the fatigue damage at wheel surface is considered. The simulation results indicate that the wheel/rail contact is full-slip under the low-adhesion conditions with braking effort. The wear amount under the low-adhesion conditions is observably higher than that under the dry condition. It is further suggested that the wheel tread is prone to suffering more serious wear and fatigue damage issues with a higher anti-slip control threshold compared to that with a lower one.

在铁路车轮上传播的胎面磨损和滚动接触疲劳 (RCF) 损伤是两个极其重要的焦点，因为它们会极大地恶化轮轨相互作用和摆动稳定性并破坏车轮表面材料，从而缩短车轮的使用寿命。车载防滑控制器本质上旨在阻止动力轮对在低附着力轮轨条件下的明显打滑。本文旨在研究不同轮轨摩擦条件下防滑控制对车轮踏面磨损和疲劳损伤的影响。为此，扩展了基于综合车辆-轨道相互作用模型的车轮磨损和疲劳损伤演化预测模型，其中使用了轮/轨非赫兹接触算法。此外，考虑了摩擦磨损对车轮表面疲劳损伤的影响。仿真结果表明，在有制动力的低附着力条件下，轮轨接触是全滑移的。低粘附条件下的磨损量明显高于干燥条件下的磨损量。进一步表明，与较低的防滑控制阈值相比，较高的防滑控制阈值更容易导致车轮踏面出现更严重的磨损和疲劳损坏问题。
