摘要
随着CAD技术和数据库技术的发展，各类智能设计理论及设计知识发现技术相继被提出，以利于知识继承和利用，提高设计的质量和效率。面向行业和过程的CAD专用系统可以有效地利用现有的智能理论进行设计知识的发现、获取和利用，满足企业的需求。
本文基于UG的应用现状制定了CAD模型质量控制标准，开发了相应软件。结合自主研究开发的型号工程知识驱动的夹具CAD系统，提出了夹具设计知识表示—挖掘—利用模型，深入研究了复杂多维关联规则挖掘的相关算法及其实现，详细探讨了夹具设计规则推理／解释机制，在此基础上开发了基于规则推理的夹具设计模块，并提出了进一步研究内容和方向。
该模块已应用于某大型航空企业国家重点型号工程的研制中，取得了良好的效果。
With the development of CAD and database technology, various intelligence theroies was presented for reusing design knowledge and promoting design quality and efficiency. Design knowledge can be discovered and acquired and utilized by CAD system facing industry application utmostely, which accord with enterprise requirement.
Based on the autual application of Unigraphics, corresponding CAD model quality control standard was formulated and implemented. With the development of knowledge driven CAMFS, the paper presented knowledge represent-mine-utilized model of fixture design, lucubrated the algorithem mining complex dimension associate rules, discussed the resoning-hermeneutic mechenism of fixture design amply, and implemented rule-resonning based fixture design modual. Finally, some opinions and advices were presented on the further research.
The module was utilized well in one super aeronautic corporation for developing national Aviation Project.
