Investigation of Transverse Surface Crack on Vibration Analysis of Rotating Shaft

Abstract:

For many years crack identification methods have been studied by number of researchers. The development of crack changes dynamic behavior of rotor system. It decreases the strength of object or material. Timely detection of a shaft crack by efficient condition monitoring system would avoid severe damage and expensive repairs due to failure of rotating machinery as well as assure the safety of personnel. The shaft crack is one of the most serious faults in high speed rotating machinery. It is important to detect them before they reach the critical size and cause total failure of the shaft. Hence attention to the study of rotating shaft with crack is required. This paper gives the general introduction to the vibration analysis method for crack detection with experimental set up. From software analysis it has shown that due to crack shaft gives different deformation values for different natural frequencies.
