- In order to solve the time-frequency feature extraction problem of the vibration signal, a fault diagnosis method based on Hilbert spectrum and singular value decomposition is proposed and applied to engine fault diagnosis. Firstly, the vibration signals are decomposed into a series of intrinsic mode functions by using empirical mode decomposition method. Secondly, Hilbert transform is applied to each intrinsic mode function and Hilbert spectrum of the vibration signal is got. Then the singular value method is applied to the Hilbert spectrum and the singular value vector is acquired. Finally, as feature vectors, singular value vectors are input into RBF network for identifying the different fault. Experimental simulation shows that this method can extract effectively the engine fault vibration signal characteristics.
