Mechanical fault diagnosis method and device, electronic equipment and computer readable medium

The invention relates to a mechanical fault diagnosis method and device, electronic equipment and a computer readable medium. The method comprises the following steps: carrying out generalized linear W transformation on a mechanical signal to generate a generalized linear W transformation time-frequency spectrum of the mechanical signal; generating a group delay of the mechanical signal at each time frequency position based on a generalized linear W transform time frequency spectrum; generating a transient extraction generalized linear W transform time-frequency spectrum based on a transient extraction algorithm and group delay; and carrying out mechanical fault diagnosis based on transient extraction generalized linear W transformation time-frequency spectrum. According to the mechanical fault diagnosis method and device, the electronic equipment and the computer readable medium, the non-stationary characteristic of the signal can be depicted more finely, and the pulse characteristic of the mechanical fault
