- Abstract:
- Modal aliasing problem exists in nonlinear and non-stationary signal processing through EmpiricalMode Decomposition (EMD ) ;Ensemble Empirical Mode Decomposition EEMD can suppress modal aliasingproblems in some extent,but added white noise can not be completely neutralized.So,complementary Ensem-ble Empirical Mode Decomposition (CEEMD) is proposed,which can reduce the reconstruction error and ex-tract the best Intrinsic Mode Function ( IMF). Then,fast fourier transformation is applied to the lMF compo-nent to derive the characteristic frequency of the fault. Analyzing the vibration signal collected by roller bear-ing experiment proved the superiority of the method and it has some practical value.
