Shafts are the components which are subjected to the hardest conditions in high performance rotating equipment used in the process and utility plants like high speed compressors, steam and gas turbines, generators and pumps etc. Although when shafts are operated in different type of conditions then serious defects can appear, but these are much suspected to cracks because of the rapidly fluctuating nature of stresses. The development of crack changes dynamic behavior of rotor system. It decreases the strength of object or material. When shaft rotates then due to defect the vibration response of the rotating shaft will more or less change. By using the additional vibration extracted from the shaft due to defect, an on-line condition monitoring system for crack detection might be developed for rotor systems. Even for smaller crack, rotating shaft creates the vibrations. So, the vibration monitoring is more useful for detecting crack in rotating shaft. This paper gives the vibration analysis of rotating shaft with different crack location & with different shaft speeds.
