IMPROVED MOMEDA METHOD AND ITS APPLICATION TO FAULT FEATURE ENHANCEMENT OF ROLLING ELEMENT BEARINGS

Aiming at the shortcomings of multipoint optimal minimum entropy deconvolution adjusted（ MOMEDA） method,which cannot automatically identify the fault impulse period and shorten the length of deconvolved signal when enhancing bearing fault features,an improved MOMEDA（ IMOMEDA） method is proposed.The...
