Application of Bistable Stochastic Resonance based on VMD in Early Fault Detection of Rolling Bearing

In order to detect the early weak faults of rolling bearings effectively,a method of adaptive stochastic resonance based on variational mode decomposition（ VMD） is proposed. Firstly,the fault vibration signal of rolling bearing VMD is decomposed into finite Intrinsic Mode Functions（ IMF）,IMF compone...
