Application of variational mode decomposition optimized with improved whale optimization algorithm in bearing failure diagnosis
The vibration signals of rolling bearings are unstable and nonlinear, with weak information on failure features and extremely low signal-to-noise ratio (SNR). To solve these problems, this paper presents a failure diagnosis method based on variational mode decomposition (VMD) optimized by the improv...
