A New Method for Weak Fault Feature Extraction Based on Improved MED

A New Method for Weak Fault Feature Extraction Based on Improved MED

Because of the characteristics of weak signal and strong noise, the low-speed vibration signal fault feature extraction has been a hot spot and difficult problem in the field of equipment fault diagnosis. Moreover, the traditional minimum entropy deconvolution (MED) method has been proved to be used...
