Vibration response-based condition monitoring and fault diagnosis of rotary machinery

Abstract

Bearings are considered as indispensable and critical components of mechanical equipment, which supports the basic forces and dynamic loads. Bearing faults can results in catastrophic failure of equipment, specially aircraft, automobile, turbine and other rotary components. An efficient and fault free performance of bearings is required because of continuous nature of operation. Any incipient failure if not detected well in time can be a costly affair which may cause significant financial losses. Vibration, temperature and acoustic signals have been used for machinery health monitoring, vibration signature being the most widely used parameter. This article overviews the vibration signals based studies conducted for monitoring the health of the rotating machinery and will be useful for practising engineers and researchers working in the field of rotary machinery.
