In order to reveal the dynamic response characteristics of the rotor system during shutdown after aero-engine blade loss, considering the blade disk moment of inertia asymmetry and the characteristics of variable speed during shutdown, the transient dynamic response analysis model of asymmetric variable speed rotor was established to analyze the transient response of rotor system during shutdown after blade loss. The results showed that when the blade was lost and the rotor passed through the resonance zone, the transient vibration response of the rotor system was intensified, accompanied by transverse natural vibration. When the asymmetric ratio of moment of inertia was 0.2, the peak response of the rotor system differed by 58% without considering the asymmetry of the disk. Therefore, for the loss of large mass blades or multiple blades, the moment of inertia asymmetry can’t be ignored, showing that the established rotor dynamics model can effectively analyze the complex vibration response characteristics of large asymmetric rotor during shutdown.
