In order to improve the accuracy of gearbox fault diagnosis
this paper adopts a gearbox fault identification method combining VMD (Variational mode decomposition) and 1D-Resnet (One-dimensional residual network). Firstly
the krill swarm algorithm is used to optimize the penalty factor α and the number of decomposition layers K in the VMD. Secondly
the VMD is used to decompose the fault signal to generate several IMF (Intrinsic mode functions)
and the correlation coefficient is used to screen the IMF component. Finally
the screened component is used as the input data of the improved residual network for network training and testing
and the fault identification result is obtained. Through the horizontal comparison with the average accuracy of VMD-random forest
VMD-CNN and other methods
the results show that the method in this paper is more accurate for identifying gearboxfault types.
