Considering the fatigue failure of the raceway,the discontinuous contact between the rolling element and the cage,the nonlinear dynamic contact model of the cylindrical roller bearing was established.The influence of the location of different failures,radial load and rotational speed on the slip characteristics of the rolling element and the cage were studied.The simulation results were compared with the theoretical solution to verify the validity of the finite element model.The results show that the rolling elements are more likely to slip in the nonload bearing area.The slip ratio of the rolling elements and the cage will be greatly increased by the peeling failure under the same working conditions,especially the slipping rate is increased most by the compound faults,while the slip rate is increased almost the same by the inner ring fault and the outer ring fault.The slippage of the bearing can be effectively reduced by increasing the radial load,however,the effect of restraining the slip is not obvious after the load is increased to a certain extent.The fatigue failure of the inner and outer rings has little effect on the slip rate of the bearing under lowspeed conditions,and the effect of fatigue failure on the slip rate is increased with the increase of the rotational speed.
