【Abstract】 The finite element model of bearing-rotor system components is modified by model modification technique.The rigid-flexible coupling model of cylindrical roller bearing-rotor system is established by using ADAMS multi-body dynamics simulation software. Based on this rigid-flexible coupling model, the slip process of cylindrical roller bearing is simulated, and the effects of rotational speed, radial load, clearance and friction on the slip rate of bearing are studied. The bearing-rotor system test bench is designed to test the slip rate of cylindrical roller bearing, and the effects of load, speed and clearance on bearing slip are studied to verify the accuracy of simulation model. On this basis, the boundary conditions which may cause slip during bearing operation are studied.更多还原
