A Study on the Knowledge based Design Process for Space Product

摘要

In this paper, an effective approach is proposed to realize the accurate acquisition of the design knowledge and rapid accomplishment of a new task in the knowledge based design process for space product. The mapping relationship between design data and design knowledge is built in the model of the knowledge based design process for space product. As a result, recessive knowledge in the design process can be obtained by using artificial neural networks (ANN). The realization of the heritage and the sharing of the knowledge improve the level and efficiency of the production design. As a case study, the acquisition of the design experience of Solid Rocket Motor shows the efficiency of the approach.
