    Abstract
  • In order to effectively pick out the impact-rub fault signal of aeroengine rotor, improve fault diagnosis veracity, the impact-rub signal was transformed to phase space by using generalized S-transform, the features of fault signal were detected in phase space, and the results obtained by using generalized S-transform(GST) and continuous wavelet transform(CWT) were compared. Comparison result shows that the time-frequency localization characteristics and singular points of impact-rub signal are more distinct in GST domain than in CWT domain, the impact-rub points are easier to be detected, GST has strong capability in noise reduction, and the separation of signal and noise is also available in GST domain.
