To analyze the vibration and stress characteristics of the rolling bearing raceway fault evolution process,a two-dimensional fully flexible explicit finite element model of the rolling bearing is established by ANSYS/LS-DYNA with full consideration of radial load,rotational speed,friction and other influencing factors,and the simulation analysis of the outer and inner raceway fault evolution is carried out.The analysis results show that the error between the calculated fault characteristic frequency and the theoretical solution is less than 1％,the vibration response and stress level of the bearing increase with the evolution of the raceway fault,and under the same fault size,the influence of the inner raceway fault on the vibration response and stress is greater.
