Considering the deformation of bearing components and actual loaded forms, the explicit d namics solver LSDYNA was adopted to calculate d namics response of bearing w hich operate from acceleration to constant speed and w as subjected to three kinds of radial load. The result shows that the bearing experienced strong vibration in acceleration phase w hich extends to the beginning of constant speed. The equivalent stress w as much higher than the ield strength of bearing steel regardless of radial load. With the increase of running time of constant speed of the bearing, the vibration w as w eaken obviousl and the bearing entered a stable working status. The fluctuant range of the radial displacement of the shaft is smaller and the distance betw een bearing ax is and the
