摘要
滚动接触疲劳是受到循环载荷的轮轨接触面的主要失效机制。其损伤机理和相关的模型算法有很多种 ,文章对其进行了具体分析 ;并从材料本身和外部条件两个方面对影响车轮滚动接触疲劳损伤的因素进行了探讨 ,提出了今后的研究方向。
Rolling contact fatigue has long been recognized as principal failure mechanism in wheel/rail luricated contact subjected to cyclic loading.There are many damage mechanisms and models on it. in this paper,the theories are analyzed in detail.The influence factors are discussed from wheel material itself and exterior conditions and put forward the future orientation.
