Abstract
This paper presents the vibrational analysis of a rotating cracked shaft in viscous medium. Virtual mass effect and damping effect on rotating shaft due to viscous fluid are analyzed with the help of Navier Stoke's equation. Analyses of the cracked portion of the shaft for fundamental frequency are done with the help of influence coefficients, stiffness elements, and boundary conditions at the cracked section. It is observed that, because of the crack and viscous fluid, there is a change in critical speed and amplitude of vibration.
