| Abstract: | The method to extract the qualitative failure features from vibrational time-scries signals of rotaries, with wavelet transform and theory of delay embedding analysis. is discussed. The method has been used to analyze the numerical data of the common failure information collected from an experimental rotor system. The wavelet representation and the chaos dynamics features of several common failures of rotaries are given. |
