FAULT DIAGNOSIS OF BALL BEARING BASED ON ELCD PERMUTATION ENTROPY AND RVM
Aiming at the no stationary characteristic of a gear fault vibration signal, it proposes a recognition method based on ELCD(Ensemble local Characteristic-scale decomposition) permutation entropy and RVM. First, the vibration signal was decomposed by ELCD, then a series of intrinsic scale components...
