摘　　要：从汽车焊装夹具的结构出发,在国内外研究现状的基础上,指出了焊装夹具研究方面的不足,详细论述了汽车焊装夹具智能设计系统研究与开发的意义。应用成组技术(GT)编码并构建智能系统的基础类库,采用CBR和RBR推理模式相结合的方法,给出了系统开发的设计流程图。利用相似度算法、变换矩阵算法,并通过NX8.0软件建模,开发VC++6.0辅助工具的动态链接库,实现了汽车焊装夹具智能设计系统。此系统可调用汽车焊装夹具元件库、模块库、案例库的三维组件,实现了标准件库的可移植性,满足了设计周期短、设计制造失误少、设计成本低的设计要求。On the basis of the research overview of automotive weldingfixtures, it notes the disadvantages in current research, which discusses the significance of automotive research and development of intelligent design system for welding fixture. It adopts group technology （GT） to code and build foundation class library of intelligent system. Using hybrid reasoning method of RBR and CBR, the flowchart of intelligent design is given. The intelligent design system for welding fixture is developed in the form of dynamic link library of VC＋＋6.0 based on similarity algorithm, transformation matrix algorithm and models in NX8.0 CAD software. The system can export the three dimensional components from component database, module database and case database of welding fixture, which satisfy the portability of standard pans library and the design requirement of shortening design period, decreasing the error of design and manufacture and design cost.
