Abstract:

In view of the complex equipment fault with presents the characteristics of multiplicity, correlation and fuzziness, this paper analyzes the evolution law of the equipment health state, constructs the fault risk scale by using the adaptive fuzzy neural network and failure mode, effects and criticality analysis, and realizes the quantitative description of the fault risk degree of complex equipment state equipment health classification. Experimentally, the model proposed in this paper has significant advantages over the traditional fault prediction and quantitative method of fault risk degree, and realizes the dynamic feedback of the whole life cycle equipment from design, production, deployment and use to retirement, which is of great significance for improving the comprehensive support ability of complex equipment.

Key words: double label fuzzy neural network, failure prediction, equipment health, failure risk scale (FRS)
