Adaptive variational mode decomposition based on Archimedes optimization algorithm and its application to bearing fault diagnosis

•A novel index is proposed to evaluate the signal complexity.•The envelope signal is Fourier transformed twice in the objective function.•A novel adaptive VMD method based on the AOA is proposed. Variational mode decomposition (VMD) is widely used in rotating machinery fault diagnosis. However, the...
