【Abstract】 The concept and development of intellectural CAD are introduced and the characteristics of artificial neural networks(ANNS) are analyzed in this paper. Aimed at the problems existed in current expert systems of machine design this paper put forward a point of view that is is an effective way for carrying out intellectural CAD by appling ANNS into the design of expert system. The application of ANNS in the aspects of conceptual design, simulation of thinking in terms of images in designing process, acquisition and representation of knowledge and simulation of recalling problems are introduced.更多还原
