CONDITION MONITORING VIBRATION ANALYSIS OF DEFAULT SHAFT

Condition Monitoring is an advanced and very useful tool of predictive maintenance techniques. When a machine fails or break down results in catastrophic failure, For this reason early detection, identification and correction of machinery problems is paramount to anyone involved in the maintenance of industrial machinery to insure continued, safe and productive operation. In order to run the machines efficiently condition monitoring of machines is important. Vibrations are found almost everywhere in rotating shaft. Shaft vibrates due to unbalances, misalignments and default in Shaft. The disturbance in shaft will be vibrated using actuator and then the vibratory motion in the shaft is sensed by accelerometer. The accelerometer will send the sensed vibration data to F.F.T Analyser which can change the sensed data by accelerometer to meaningful data shown in the PC, such as; frequency, Amplitude, displacement due to misalignment, defects are compared, so that premaintenance can be done. so in this paper shows the behaviour of shaft under normal & defects condition & its effects on its performance is shown.
