An improved variational mode decomposition and its application on fault feature extraction of rolling element bearing

HIGHLIGHTS

• who: Guoping An et al. from the School of Electrical Engineering, Beijing Jiaotong University, Beijing, China have published the paper: An Improved Variational Mode Decomposition and Its Application on Fault Feature Extraction of Rolling Element Bearing, in the Journal: Energies 2021, 14, x FOR PEER REVIEW of /2021/
• what: The Ensemble EMD (EEMD) with the noise assisted method was developed, which can eliminate the mode mixing by adding white noise . In this paper, an improved fault feature extraction algorithm based on VMD is presented. A comprehensive study of CWRU data has been provided in the . . .
