Abstract

The bearings are widely used in the rotating machinery systems to support the mechanical, structural for system. In a high rotating speed, the spindle to be stable rotating is dependent on a high performance bearing. Therefore, the dynamic characteristic of a ball bearing is very importance and need to study. In this work, the dynamic characteristic of a ball bearing is focused to study. Because the geometric of ball bearing are so complex, the finite element analysis is employed to investigate. By using the finite element analysis software ANSYS, the bearings meshed model can be setup. The dynamic properties, natural frequency and mode shape of ball and global system, can be studied to improve the high spindle rotating stable performance. Numerical indicates that the stress, strain and dynamics of the ball bearing system can be investigated in this finite element model.
