A Novel Method for Adaptive Multiresonance Bands Detection Based on VMD and Using MTEO to Enhance Rolling Element Bearing Fault Diagnosis

Figure 16

Analyzed results of the experimental vibration signal in Figure 15(a) by the proposed method: (a) power spectrum of five modes decomposed by VMD; (b) the number of iterations with central frequencies; (c) kurtosis value of five decomposed modes; (d) waveform of the first mode with the maximum kurtosis value; (e) waveform of the second mode with the third maximum kurtosis value; (f) waveform of the third mode with the second maximum kurtosis value.
