Fault Detection of Ball Bearing Using Finite Element Analysis

Abstract

During the last decade’s vibration based damage detection methods have attracted the most attention due to their simplicity for implementation.  This research mainly deals with detection of faults through vibration analysis by using Finite element method with the help of analysis software. There is change in mode shapes and relative natural frequencies due to fracture of ball radius. By examining these changes in ball radius and its frequencies can be identified. It has been noticed that when the ball radius decreases relative natural frequency and also there is a deviation in the mode shape. These methods provide the knowledge towards the characterization of the damage to the structure.
