A Review on Bearing Fault Detection by Vibration Signature Analysis

K H Munde1, S B Thakre

Vibration analysis is one of the most usual methods utilized to evaluate the conditions of bearings in an operating machine. Such measurements may be used for machines with bearings in new condition as well as for machines whose bearings are deteriorating and approaching the end of their useful lifespans. If a machine’s vibration response to known excitation forces has been determined through techniques such as finite element analysis and modal analysis, then vibration measurements during service can determine the dynamic characteristics of the forces working on the car. Vibration data can likewise be used to know forcing characteristics and the condition of machine parts, mainly bearings. The paper highlights the work done by various researchers for bearing fault detection.
