Theoretical and Experimental Investigation Of a Shaft Disc System With a Crack

This work proposes the vibration analysis for the periodically time-varying rotor system with Transverse crack. Identification of a crack in a rotor is major issue in industries. Sudden failure of the rotor system may lead to huge maintenance cost and production hault.Therefore it is necessary to diagnose the problem while operation is carried on so that at appropriate intervals maintenance can be done.This work uses Vibration Signature Analysis to analyse the difference between responses of sound shaft and a cracked shaft. Based on the inference of the two responses it can be predicted at what time the shaft should be changed before it leads to catastrophic failure. The details of experimentation and analysis are given in the following contex
