摘要
用数值分析方法分析了单轮对的摇头运动对其左右轮轨滚动接触斑上蠕滑率／力的影响。在轮轨滚动接触蠕滑率／力关系分析方面，利用了Ｋａｌｋｅｒ的三维弹性体非赫兹滚动接触计算模型。通过分析计算可知，轮对摇头角运动参量是影响轮轮之间横向蠕滑力的主要因素。
The effects exerted by the yaw motion of a single wheelset on its creep forces/creepages are investigated in the study. The numerical analysis of rail/wheel rigid contact is briefly intruduced, and Kalker's theory of theree dimensional elastic bodies in rolling contact with Non Hertzina form is employed and analyze the relationships of creep forces and creepages. According to the numerical results abtained, it is found that the yaw angle of wheelset is a key factor affacting on the lateral creep forces between wheelset and rails.
