In this paper, the nonlinear dynamical behavior of a horizontal Jeffcott rotor system with a transverse crack is analyzed numerically. A new acceleration scheme is suggested to reduce shocks to the rotor and diagnose the existence of cracks. Particular stress is laid on the analysis of the spectrum of transient and stable response by using a new approach of signal processing, which could erase both the gravitational effect and the free vibration with inherent frequency for the purpose of accurate crack detection.
