摘　　要：为了建立自动化的注塑产品成型性分析系统 ,要根据注塑产品的 BRep模型自动提取其设计特征。本文提出了一种注塑产品设计特征树构造算法 ,该算法应用正向推理技术实现设计特征的识别 ,并以特征树结构记录产品的设计特征。经实践证明 ,该算法具有高效。To establish an automatic system to analyze injection product forming performance, design features of injection product should be recognized from product's Brep model. In this paper, knowledge reasoning is applied to recognize design features, and then the data tree structure is used to record design features. This design tree construction algorithm, which has been successfully applied to implement a forming analysis system, can separate knowledge from codes so that it is suitable for recognition of complex design feature.
