This paper illustrates the process of equipment maintenance support information analysis from the input and output of model perspective. It summarizes two kinds of uncertainty forms, probable values and interval values. The entropy theory is used to measure uncertainty in this paper. Then it explains the interval value uncertainty spreading mechanism in equipment maintenance support information analysis...
In order to track degradation trend of bearing performance using shock feature hidden in vibration signal, a best Morlet wavelet transform-based extraction method of full information energy entropy was proposed through integrating Morlet wavelet transform technology and full information technology. The optimization of Morlet wave shape factor was controlled by the minimum Shannon entropy. The information...
