Constitutive dynamics of a cracked rotor supported on sliding bearings are modeled and analyzed by Wavelet Transform. The effect of the ensuing non-linear disturbances, namely, oil film forces, rotor stator rub forces, and a switching crack on the rotor shaft is numerically simulated. Subsequently, the system response is evaluated under various scenarios and the results reported. A sensitivity analysis on various system parameters is performed and discussed to emphasize the modeling. The current technique as a tool for condition monitoring of rotors has been demonstrated by analysis in this paper.
