Dynamic characteristics of a cracked rotor with a periodic excitation force are investigated. Due to the open-close mechanism of the rotor crack, the equations of motion of a cracked rotor have linear and nonlinear parametric terms. When a periodic excitation force is applied to a cracked rotor, various kinds of resonances, which are not observed in a symmetric rotor and an asymmetric rotor with linear spring characteristics, occur due to the unique spring characteristics of a cracked rotor. We clarify characteristics of these resonances theoretically and axperimentally. These results enable us to detect a crack on-line without stopping the system.
