A diagnostic model of a crack in macro state based on analysis of parametric resonance and a wavelet transform is proposed in this paper. Parametric resonance and sub-harmonics are deliberately adopted into the model and treated by a Harmonic Wavelet. The model is considered for analysis of torsional vibration. A parallel and suitable harmonic time series is derived to simulate the dynamics of the crack and consequently the influence of breathing on the system. The model is analytically demonstrated to be good for investigating a balanced cracked rotor in torsional vibration.
