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.
