摘　　要：分析了汽车总体设计阶段的任务,以参数化绘图技术和专家系统技术为基础,结合数据库技术建造了基于参数化和专家系统技术的汽车总体设计CAD系统·该系统可以以人机交互的方式完成整车方案设计的全过程,最终给出符合设计目标的总布置图的三维模型;给出了该系统的总体结构,简述了设计参数选择专家系统模块的实现方法和功能,详述了基于UGII,利用其二次开发工具开发的各参数化图库的功能和建造方法·The design tasks in vehicle overall design stage were analyzed. Based on the parametrizing technology and expert system technology the vehicle overall design CAD system was build combined with the database technology. In manmachine interactive mode, this system can define the design plan and give the overall layout graph in three dimensions. The overall structure of the system was given. The building and function of the overalldesign parameterselecting expert system were introduced briefly. The building and the function of the parametric graphical libraries were described.
