Abstract EN
A novel fault diagnosis method, named CPS, is proposed based on the combination of CEEMDAN (complete ensemble empirical mode decomposition with adaptive noise), PSM (periodic segment matrix), and SVD (singular value decomposition).
Firstly, the collected vibration signals are decomposed into a set of IMFs using CEEMDAN.
Secondly, the PSM of the selected IMFs is constructed.
Thirdly, singular values are obtained by SVD conducted on the space of PSM.
Fourthly, the impulse components are enhanced by the singular value reconstruction with the first maximal singular value.
Finally, the squared envelope spectra of the reconstructed signals are used to diagnose the wheelset bearing faults.
The effectiveness of the proposed CPS has been verified by simulations and experiments.
Compared to the well-known Hankel-based SVD, the proposed CPS performs better at extracting the weak periodic impulse responses from the measured signals with strong noise and interferences.
