Abstract Aiming at the problem that it is difficult to extract the fault characteristics of the low -speed and

heavy-load slewing bearing under strong background noise a slewing bearing fault diagnosis method based
on the combination of variational mode decomposition and multipoint optimal minimum entropy deconvolu-

the optimal component of kurtosis is selected from it． Secondly the parameter T in the MOMEDA algorithm

is optimized by the grey wolf optimization algorithm and then the fault impact component of the optimal
