Abstract

This paper puts forward a vibration signal de-noising method based on LMD and Wavelet De-noise. The method de-noises the PFs separated from LMD by wavelet De-noise, and reconstitute the de-noised signal. It’s effective to de-noising diesel engine vibration signal and simulation signal. Compared with wavelet noise reduction method, the method is better at de-noising amplitude & frequency modulated signal de-noising.
