  • [PDF] Dynamic Analysis for Cage in a Ball Bearing

    A dynamic model of ball bearing is established based on the explicit dynamic method in ANSYS/LS-DYNA. The dynamic vibrations of bearing are simulated at different radial loads, rotating speeds, cage materials, and then the effects on the vibration and stress of cage are analyzed. The results indicate ANSYS/LS-DYNA is an effective tool for the dynamic analysis for cage in ball bearing.
