摘要
利用非Hertz滚动接触理论和数值程序CONTACT分析了LM,LMA,S1002和XP55四种车轮型面与我国CHN60钢轨匹配时的轮轨黏滑特性.数值结果表明:四种车轮型面与CHN60钢轨匹配时的轮轨接触斑黏滑特性明显不同,车轮型面对轮轨接触斑面积、黏滑区分布、轮轨摩擦功等有较大影响;LM型面与CHN60匹配时的蠕滑区面积和轮轨摩擦功较大,且接触斑更容易达到饱和状态;LMA型面与CHN60匹配时的黏滑特性较佳,其接触斑面积、黏着区面积较大;S1002型面与CHN60匹配时的黏滑特性较XP55型面要好.
The stick-slip behaviors of wheel-rail between LM, LMA, $1002, XP55 wheel profiles and CHN60 rail in static rolling contact were analyzed according to the rolling contact theory of three-dimensional elastic bodies with non-Hertz form and numerical program of CONTACT. The numerical results indicate that the stick-slip characteristics of wheel-rail between LM, LMA, S1002, XP55 wheel profiles and CHN60 rail are different. The wheel profile has an obvious effect on the area of the contact zone, the stick-slip distributing and the friction work of wheel-rail. The stick-slip characteristic between the LMA wheel profile and the CHN60 rail is better and the areas of the contact zone and stick zone are larger. The stick-slip behaviors between S1002 wheel profile and CHN60 rail are better than those of the XP55 wheel profile.
