摘　　要：在基于专家系统的智能ＣＡＤ系统中，知识的表示、组织和知识库管理是一个很重要的问题。它直接影响到设计的效率和设计质量。本文讨论了机械设计过程的特点，分析了设计对象中知识的不同使用目的，提出用统一的方式来表示设计知识和设计过程知识，并用面向对象和分组组织的方法来组织和管理知识库。基于这些方法，开发了机械智能ＣＡＤ支持工具——ＴＦＭＩＣＡＤ系统，该系统既有较高的设计效率，又能保持对不同设计条件和不同问题的较好的适应性。The knowledge representation, organization, and knowledge base management are very vital in the Intelligent Computer Aided Design technology based on Expert System. They directly affect design′s efficiency and quality. This paper discusses the features of mechanical design process, analyses the usage of knowledge in design, then proposes an unified model to represent all of the design knowledge, including those of design object and design process, an object oriented and group based model to organize the elements in the knowledge base. A system named TFMICAD is developed on the basis on these models. It has high efficiency and good adaptability to different design conditions and different design problems, and is easly managed and maintained.
