Study on injection molding collaborative design technology based on knowledge and numerical simulation case

摘要

To improving unilateral defect in CAE technology of injection molding, the paper advances collaborative design method based on knowledge and numerical simulation case for injection molding design. According to the application of feature technique to the modeling of injected part and injection molding more and more comprehensively, this paper puts forward a knowledge model of injection molding design based on feature, which is called FEATURE, and FEATURE is also applied to express the model of CAE numerical simulation case successfully. The collaborative reasoning model includes case-based reasoning (CBR), rule-based reasoning (RBR) and the both collaborative mechanism together, which includes the information exchange during the reasoning and the optimized choice of the reasoning result. The study shows that the technique of collaborative design based on knowledge and numerical simulation case has achieved effectively the design reuse of CAE results and shortened the design cycle of injection molding.
