摘要
结合汽车覆盖拉延件工艺要领设计，分析了工艺设计知识的特点和表达方式，指出把人工神经网络作为一种知识形式，纳入知识库的必要性和可行性。以此为基础，建立了面向对象知识库的原型，并将其与传统知识库进行了比较。
In this paper, the characters and representations of technical design knowledge are discussed, combined with technical essential design for automobile stretching panel. The necessity and feasibility of including artificial neural network (ANN) as a part of knowledge base are analyzed. Based on a prototype object oriented knowledge base (OOKB), the differences between OOKB and traditional KB are pointed out.
