产品生长型设计及其关键技术研究

计算机辅助概念设计是机械设计领域的研究热点。在生长型设计理论的基础上提出了生长型设计过程模型；研究了CAD系统中支持生长型设计的关键技术：产品信息数据结构，设计知识库建模和概念结构匹配为实体结构技术；在此基础上开发了相应的概念设计自动化软件；通过工程实例验证了上述理论和技术的有效性和实用性。

Research on the Growing Design Process of Products and the Key Technology

The mechanical design was focusing on the Computer-Aided Conceptual Design. Based on the growth theory of the product design, the model of growth design process was presented. The key technology like the data structure of product, knowledge library of the design and conceptual form-to-detailed form mapping were studied for supporting the growth design process in the CAD systems, and the automated software of conceptual design was developed. The example of designing a project problem explained the availability and practicability of the theory and technology mentioned above.
