Based on the simple hinge crack model, the dynamic equation of a rotor containing transverse crack and initial deflection is modelled in dimensionless form, which can be applied to the vibration analysis of cracked rotor with different parameters at stationary, transient and nonlinear state. By analytical solution, the frequency components of the cracked rotor with initial deflection are compared with those without initial deflection, and the subcritical resonance is discussed. The stability of the cracked rotor with initial deflection is investigated using Floquet theorem, and the influence of different stiffness variation and damping ratio on stability is analyzed, which can provide a basis for identification of cracked rotor.
