ABSTRACT

This paper at first reviews the existing research of traditional PHM in life prediction aspect and proposes an experiment-based PHM framework to overcome the abovementioned shortcomings. The usage-oriented life prediction model set is given at the in-field development phase and integrated with operational data to do health evaluation and maintenance decision-making. The rest of this paper is organized as follows. In Section 2, the research status of life prediction methods is analyzed and the existing problems are pointed out. The new framework is presented in Section 3 and three stages are mainly introduces, i.e. pre-design, after-design and field use, with related research contents for life prediction modelling. The flexibility of the framework is verified by case studies in Section 4. Section 5 concludes this paper.
