A SINGULAR INTERVAL RECONSTRUCTION LOCAL MEAN DECOMPOSITION AND ITS APPLICATION IN BEARING FAULT DIAGNOSIS OF RECIPROCATING COMPRESSOR (MT)

Aiming at the mutation in demodulation of the envelope estimation function, a local mean decomposition method for singular interval envelope reconstruction is proposed. This method determines that the reason for the sudden change in the demodulation of the envelope estimation function is the interse...
