英文摘要	A 2-DOF dynamic model for rolling bearings was built to reveal their vibration response mechanism more correctly due to their inner race surface existing localized defects under action of radial loads. The process of rolling elements entering defective area until leaving was described as four events including entry event, impact one, exit one and load compensation one. Appropriate excitation force functions were constructed according to the corresponding events. Considering the effects of time-varying displacements due to defects and bearing's stiffness-varying vibrations on bearing's dynamic characteristics, based on Hertz contact theory, the dynamic model for a bearing with local defects was established. The fourth-order Runge-Kutta method with varying steps was used to solve the dynamic equation and obtain the model's vibration response signals. The effect laws of defect size and rotating speed on bearing system's vibration acceleration amplitude were investigated. The validity and feasibility of the dynamic model were verified using faulty bearings' tests. © 2018, Editorial Office of Journal of Vibration and Shock. All right reserved.
