Weak Feature Extraction of Rolling Bearing Fault Based on Generalized Variational Mode Decomposition

Aiming at the deficiency of variational mode decomposition (VMD) in on-demand extraction of weak feature components, a generalized VMD (GVMD) is proposed to extract the weak features of rolling bearing faults. GVMD has excellent multi-scale and fixed frequency decomposition performance in the freque...
