Crack identific in rotors with full spectrum

Abstract

Condition based maintenance is now a days recognized as the most efficient strategy for carrying out maintenance in industrial machineries Fatigue cracks in the shaft are a very common but catastrophic fault as accidents in turbine rotors have been reported since 1950s Also the shaft failure due to fatigue crack causes increase in downtime and maintenance costs Condition monitoring employs methodologies broadly ranging from the signal based and model based methods to the model testing and n
