VIBRATION - A TOOL FOR MACHINE DIAGNOSTICS AND CONDITION MONITORING

Vibration is an effective tool in detecting and diagnosing some of the incipient failures of machines and equipment. The present paper deals with the basic principles, which may help in identifying its diagnost ic ability, the scope of its diagnostic capabilities, the instrumentat ion in vogue for its monitoring and the state-of-the-art of the monito ring techniques and programs. A few case studies are also given to ill ustrate how machine troubles/failures are diagnosed with the help of v ibration signatures.
