Abstract
A multi-spectrum fusion decision fault diagnosis method for a high-speed electric multiple-unit bearing, including the steps of collecting, by an acceleration sensor vibration acceleration signals of a high-speed electric multiple-unit; performing multi-method spectrum analysis on vibration acceleration signal data of a plurality of faults under a constant working condition, and marking the data to construct a spectrum data set; extracting inherent fault features of the spectrum data set to form a fault feature data set; performing weight fusion on spectrum fault features of different methods to construct a spectrum fault feature function, and fusing each set of spectra in the spectrum data set into a data point; using a criterion that a fisher discrimination ratio minimizes an intra-class spacing and maximizes an inter-class spacing to seek an optimal weight combination under the data set, so that fusion data points distinguish the different types of faults to a maximum degree.
