四种成分车轮钢的耐磨性及疲劳特性
Abrasion Resistance and Fatigue Properties of Wheel Steels with Four Kinds of Chemical Compositions
摘 要
根据赫兹接触理论, 在实验室条件下采用JD-1型轮轨模拟试验机进行滚动模拟试验模拟现场轮轨相互摩擦的过程, 对相同条件下四种成分车轮钢的耐磨性及疲劳特性进行了研究。结果表明: 车轮材料的碳含量越高, 其硬度越高, 相同条件下磨损量越小, 磨痕表面附近的塑性变形层越薄, 抗磨损性能越好; 高含碳量材料中的裂纹扩展较深, 疲劳损伤严重, 低碳含量材料的磨损量大, 磨痕表面附近的塑性变形明显, 由于部分刚萌生的微裂纹被磨去, 疲劳损伤较轻。

Abstract
The friction interaction process of wheel and rail under practical condition was simulated by rolling simulation test using a JD-1 wheel/rail simulation facility according to Hertz simulation theory, and the abrasion resistance and fatigue properties of wheel steels with four kinds of chemical composition were studied under the same conditions. The results show that the higher the carbon content, the higher the hardness, the less the wear quantity, the thinner the plastic deformation layer nearby wear surface and the better the abrasion resistance. The crack propagation for wheel material with a higher carbon content was deeper and fatigue damage was more severe, and wheel material with a lower carbon content appeared more wear quantity and obvious plastic deformation nearby wear surface, but its fatigue damage was slight because of the removal of a part of just-initiated micro cracks.
