摘要

摘要: 随着车辆的运行，车轮踏面会出现不同程度的磨耗，为研究磨耗状态下车轮与钢轨之间的静态匹配性能，利用轮轨接触几何关系和非赫兹滚动接触理论，计算不同磨耗程度的车轮对轮轨接触几何参数和接触力学特性的影响，并与CHN60钢轨的计算结果进行对比.分析结果表明：轮对横移小于4 mm时，车轮磨耗程度越大，车轮上接触点的横向分布宽度越大，60N钢轨的接触点横向分布宽度明显小于CHN60钢轨，对提高车辆运行稳定性有利；车轮磨耗程度越大，轮轨磨耗指数越大，60N钢轨的轮轨磨耗指数较小，有利于轮轨廓形的保持能力.车轮磨耗程度越大，位于表面滚动接触疲劳区的范围越大，相比CHN60钢轨，60N钢轨位于表面滚动接触疲劳区的情况较少，相同条件下，能够减少轮轨滚动接触疲劳伤损的发生.

Abstract: Over time, the running of vehicles results in different degrees of wear on the wheel treads. To study the static matching characteristics between the worn wheel and the rail, the wheel-rail contact geometry relationship and non-Hertz rolling contact theory were used to analyse the effects of worn-wheel profiles on the wheel-rail contact geometry parameters and contact behaviour. The results were compared with those of CHN60 rail and analysed. The results indicate that when the lateral displacement of the wheel set is less than 4 mm, the degree of wear on the wheel is greater, and the lateral distribution width of wheel-rail contact points on the wheel is larger. The lateral distribution width of the wheel-rail contact points of 60N rail is significantly less than that of the CHN60 rail, thereby improving the vehicle's running stability. The wheel-rail wear index increases with the degree of wheel wear. The wheel-rail wear index of 60N rail is smaller, which improves the ability to maintain the wheel-rail profile. A greater degree of wheel wear corresponds to a greater surface rolling contact fatigue area. Compared with CHN60 rail, the number of cases located in the area of surface rolling contact fatigue of 60N rail is less, which can reduce the rolling contact fatigue damage under the same conditions.
