Optimal Intrinsic Mode Function Based Detection of Motor Bearing Damages

Optimal Intrinsic Mode Function Based Detection of Motor Bearing Damages

This paper proposes a model which uses the greedy algorithm to select the optimal intrinsic mode functions (IMFs) of the empirical mode decomposition (EMD), namely the greedy empirical mode decomposition (GEMD) model. The optimal IMFs can more sufficiently represent the characteristics of damage bea...
