Add to ORKGIn this work a computational simulation is utilized to investigate the steady-state response of a two-crack rotor system supported by radial active magnetic bearings on an excitation by centrifugal forces of discs unbalances. The static deflection of a shaft is considered larger than vibration amplitude of a shaft and therefore a so-called breathing behaviour of cracks is introduced. Parametric study has been carried out in order to investigate influence of different values of the angle between cracks on the steady-state response of a rotor system. The results presented in this work can therefore help with detection of cracks in the shaft
