An enhanced diagnosis method for weak fault features of bearing acoustic emission signal based on compressed sensing

An enhanced diagnosis method for weak fault features of bearing acoustic emission signal based on compressed sensing

Aiming at the problems of data transmission, storage, and processing difficulties in the fault diagnosis of bearing acoustic emission (AE) signals, this paper proposes a weak fault feature enhancement diagnosis method for processing bearing AE signals in the compressed domain based on the theory of...
