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.

关 键 词:车轮型面  轮轨  黏滑  滑动量

Abstract:The stick slip behaviors of wheel rail between LM, LMA, S1002, 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.
Keywords:wheel profile  wheel-rail  stick-slip  slippage
