摘要:
在JD-1型轮轨模拟试验机上研究了干态下两种钢轨的滚动磨损与疲劳性能.结果表明:不同工况下U71Mn钢轨磨损量大于PD3钢轨,U71Mn钢轨表现出更好的抗疲劳性能;磨损与疲劳裂纹损伤表现为相互争竞与制约的耦合关系;增加磨损率能降低轮轨疲劳裂纹损伤.

Abstract:
The rolling wear and fatigue behaviors of two kinds of rail steels were investigated under dry condition using JD–1 wheel/rail simulation facility. The results indicate that the wear volume of U71Mn rail is larger than PD3 rail’s. However, U71Mn rail has better resistance to fatigue damage. The relationship between wear and fatigue crack damage of wheel/rail is manifested as mutual competitive and restrictive coupling mechanisms. Increasing wear rate can alleviate fatigue crack damage of wheel/rail.
Key words:  wheel/rail  wear  fatigue  crack  prevention measure
