Rotating Machinery Vibration Signal Processing And Fault Diagnosis Based on LMD

There are abundant of fault information in rotating machinery vibration signal. On account of the nonlinearity and non-stationarity, the paper first does pre-process to the vibration signal using wavelet threshold denoising method and this method can bring a smooth signal. Then it decomposes the vib...
