Shaft cracks in a rotor system may lead to destructive failure, if undetected at the right time. The transient vibrations of a rotor system with transverse breathing crack during rotor shut-down has been analyzed using Finite Element Method (FEM) for flexural vibrations. Since the vibration signals during shut-down are non-stationary, the continuous wavelet transform (CWT) has been used to extract the crack feature when the rotor is decelerating through critical speed during shut-down. A parametric study for...
