Abstract: In this paper, a new fault feature extraction method is presented based on wavelet transform and blind source separation. At first, wavelet transform is employed to de-noise measured signals to remove the process noise. Then blind source separation based on second order statistics is used to extract blind source signals of the process. The simulation and experiment testing results show the proposed method that compare with other method based on blind source analysis directly with process information can effectively extract the quantitative feature extraction. Finally，the signals of rotor vibration with noise interference were separated successfully using the proposed method.
