%X Approaches of qualitative analysis, multiple scale analysis and numerical simulation have been used to study properties of cracked rotor vibrations in the present paper. It has been shown that transient components of cracked rotor vibrations are ideal symptoms suited to the early detection of fatigue cracks of rotors. It has also been demonstrated that the method of multiple scales is an effective approach toward the study of parameter excited vibration systems with abrupt parameter variations.
