Abstract: This paper presents recent developments of techniques, based on vibration signature analysis to detect the fault in a machine. This paper shows vibration signature analysis implemented to detect fault in various machineries such as gear, rolling element bearing, journal bearing, induction motor, centrifugal pump and beam. The authors do not intend to provide an exhaustive discussion about machine faults but only detailed overview of rotating parts vulnerable to fault. In addition, advantages of advanced vibration signature analysis techniques over traditional one have also been discussed.
Keywords: machine fault, condition monitoring, vibration signature, preventive maintenance.
