Abstract
A modal formulation is used to investigate the vibrational behavior of flexible single or coupled rotors containing a transverse crack. A theoretical model has been developed to simulate the crack mechanism. The transformed time variable system is numerically integrated. The modal analysis shows particularly the strong dependence of the vibrational behavior on the crack position. The vibrations, excited by the crack, are independent of the unbalance.Keywords
