摘      要：正In a rotor system, a transverse crack on the shaft will take on distinct vibrational behavior during the rotating process. This may be helpful for detecting the existence of the crack. For the purpose of investigating the problem more clearly, we take the Jeffcott rotor model, with a disk on the middle of the shaft, a transverse crack adjacent to the disk. While the shaft rotating, the crack will change from opening to closing. This directly leads to the stiffness terms changing with time and
