Research on Process Modeling of Rockets Design Based on Knowledge Reuse

Knowledge reuse is an urge requirement of shortening cycle, improving quality and reducing cost in the rockets design process. In this paper, the knowledge application content in rockets overall design process is analyzed firstly. Then a design process model throughout requirement analyzing, function design, principle solving and structure design is proposed, in which the main purpose is to reuse knowledge effectively. Finally modeling technologies are studied comprehensively in each phase of rockets design process and a universal expression of design process is put forward based on computer aided design technologies. Our work provides a reference and guidance of integration methodology for knowledge reuse and sharing in aerospace products design process.
