摘　　要：针对角接触球轴承几何结构特征,建立一种基于复杂工况下角接触球轴承动态响应分析模型,并考虑角接触球轴承非线性接触特征的影响。将考虑能量损耗的耗散接触力模型和Coulomb摩擦力修正模型引入到角接触球轴承动力学方程中,采用Newton-Rapson法获得含间隙的角接触球轴承动力学特性,并在滚动轴承实验台上进行动态响应特征实验,分析不同工况下间隙对角接触球轴承动力学特性的影响规律。计算结果表明:间隙的引入增加了角接触球轴承元素之间的非线性接触特征,并会引起高频冲击,而工况条件的变化会引发角接触球轴承动态响应的变化。According to the geometric characteristics of angular contact ball bearings,a dynamic response analysis model of angular contact ball bearings based on complex working conditions was established with consideration of the influence of nonlinear contact characteristics of angular contact ball bearings.The dissipative contact force model considering energy loss and the Coulomb friction correction model were introduced into the angular contact ball bearing dynamic equation,the dynamic characteristics of angular contact ball bearings with clearance were obtained by Newton-Rapson method,the dynamic response characteristic experiment was carried out on the rolling bearing test bench,and the influence law of clearance on the dynamic characteristics of angular contact ball bearings under different working conditions was analyzed.The calculation results show that the introduction of clearance increases the nonlinear contact characteristics between the elements of angular contact ball bearings and causes high-frequency shocks,while changes in operating conditions will initiate changes in the dynamic response of angular contact ball bearings.
