摘要

An improved bubble entropy called multiscale bubble entropy (MBE) is proposed based on the multiscale processing, and then the application of MBE in bearing state assessment is investigated. Firstly, the MBE features are extracted from the collected vibration signals of the bearing with the whole life, and then dimension reduction is performed with principal component analysis (PCA). Secondly, a p...
