Based on the recently proposed method for nonlinear and non-stationary vibration signal, variational mode decomposition (VMD), an adaptive multiscale fuzzy entropy (AMFE) method is introduced in this paper. Firstly, the VMD method is used to decompose the vibration signals of rolling bearing into a number of intrinsic mode functions (IMFs). Then the fuzzy(More)
