The field observations and collection of relevant information of curves with different radii are carried out aiming at the rolling contact fatigue (RCF) of U75V heat-treated rail on the curved section of Tangshan-Baotou heavy haul railway. The important characteristics of rolling contact fatigue of rail are obtained through statistics and comparative analysis. Further, the model for initiation of rolling contact fatigue of rail integrating heavy haul train dynamics and damage function model is established to predict the effects of axle load, speed and adhesion coefficient on rolling contact fatigue of rail. It is found that the rolling contact fatigue of rail for up going heavy haul railway is alleviated with the increase of curve radius, there is severe peeling on R600 and R800 curves, the peeling on R1000 curve disappears by and large, while there is just slight cracks on R1600 curve as well as the rail damages of up going heavy haul railway are more serious than those of down going line at no-load. On the section of entering transition curve of up going railway R600, there is obvious peeling when excess of height of inner rail is 55 mm, while there is just sporadic small-size peeling on corresponding outer rail. The numerical simulation results could well explain the phenomena of field observation, which provides the key research tools for further treatment. The curve radius, axle load and profile after wear are determined to be the main influencing factors for rolling contact fatigue of rail in Tangshan-Baotou railway combining with the previous research results.

针对唐包重载铁路曲线段U75V热处理钢轨发生的滚动接触疲劳损伤,开展了不同半径曲线的现场观测和相关信息搜集,通过统计和对比分析,得到了钢轨滚动接触疲劳的重要特征,并建立了集成重载列车动力学和损伤函数模型的钢轨滚动接触疲劳萌生模型,预测了轴重、速度和黏着系数对钢轨滚动接触疲劳的影响。发现上行重载线钢轨滚动接触疲劳随曲线半径的增大而减轻,R600和R800曲线上存在严重剥离,R1000曲线上剥离基本消失,而R1600曲线上仅存在轻微裂纹,相同半径曲线上行重载线的钢轨损伤程度明显比下行空载线严重。上行线R600的入过渡曲线段上,内轨在超高55 mm时开始出现比较明显的剥离,而对应外轨仅存在零星的小尺寸剥离。数值仿真结果能很好地解释现场观测现象,为进一步治理提供了关键研究工具。结合前期研究成果,可确定曲线半径、轴重、磨耗后廓形等是造成唐包线钢轨滚动接触疲劳的主要影响因素。
