摘要：

According to the aero-engine airworthiness regulation (CCAR-33-R1), it is necessary to confirm various faults and their mechanism. With the need for higher integrality and reliability of aero-engine, a great number of problems in diagnosing rotor-stator rub fault are to be solved. Aiming at the limitation of the methods for diagnosing aero-engine rub fault based on singular value decomposition (SVD), a improved method of detecting abrupt information is presented to diagnose rub fault of aero-engine based on singularity value differences. The proposed method is verified by simulation signals and the test data of an aero-engine.
