- •
Advantage and limitation of variational mode decomposition on signal feature extraction are studied.
- •
Independence-oriented VMD is proposed for solving information loss and over decomposition problem orderly to identify wheel set bearing fault.
- •
Experimental validation and engineering applications are carried out to demonstrate the feasibility of proposed method.
