Abstract
Aiming at the problem that vibration signal is easily affected by noises in early fault identification, an aero-engine rotor system fault diagnosis method is presented based on the similarity of phase planes.Fault types are identified by calculating the similarity of phase plane plots based on the overall vibration signal parameters in various ranges and states.Simulation shows that the method proposed can efficiently resist the noises and diagnose the faults with high speed and precision, and thus has significance in practical application.关键词
