Abstract: A model-based method for rotor imbalance identification of aero-engine is proposed, including rotor imbalance fault location method based on harmonic balance method and rotor imbalance fault parameter identification method based on sensitivity method. An aero-engine gas generator rotor system in simulation is employed for validation, and an experimental investigation is carried out to verify the effectiveness of the method. The results show that this method can accurately identify the location, amplitude and phase of the imbalance in the aero-engine rotor system, and the imbalance of the aero-engine rotor system can be eliminated.
