Abstract：
|
|
The drawing process is a key process of stamping forming for autobody panels,and the design of drawn parts is a bottleneck procedure to die design of panels.In order to solve the problem that lack of experience and knowledge in designing the stamping process of panels,the implementation mechanism and application method of Knowledge-based Engineering(KBE) technology is researched,and the knowledge model of drawn part based on KBE is established by summarizing expert's experience and knowledge for drawn part design.Through integrating the design rules,experience and process constraints with design of binder,addendum and drawbead,knowledge representation and reasoning of drawing part design is realized.Based on above research,the KBE-based die face engineering system is developed on the platform of Unigraphics.The successful application of KBE improves the intelligent level of drawn part design.
