摘　　要：基于行星滚柱丝杠传动副静态接触状态,采用传动副接触外形函数分析以及赫兹接触理论,提出一种研究传动副接触特性模型以及接触力分析方法,并通过有限元分析方法进行验证。结果表明,垂直于滚柱径向的接触面中接触外形函数满足二次函数特性,赫兹接触理论可用于研究传动副静态接触特性。Based on the static contact state of planetary roller screw drive pair, a contact characteristic model and contact force analysis method are proposed by the shape function analysis of the drive pair and Hertz contact theory. The results of finite element analysis show that the method is reasonable, and the contact profile shape function in the contact surface perpendicular to the radial direction satisfies the quadratic function characteristics, and the Hertz contact theory can be used to study the static contact characteristics of the drive pair.
