充分利用产品数据管理(PDM ) 技术的思想, 以汽车产品设计为例, 在建立零部件图形库、底盘参数数据库的基础上, 通过VB 与A utoCAD2000 软件进行二次开发, 集绘图设计、数据管理于一体, 在一定程度上实现了汽车底盘的虚拟设计, 可以快速高效地进行汽车设计和资料的查询等, 从而减轻设计人员的劳动强度, 提高设计效率。 关键词: 产品数据管理; 软件开发; 数据库; 汽车设计 Abstract: Tak ing the design of automotive p roduct as an examp le and on the basis of establish ing the components library and data base of the chassis parameters, th is article makes full use of the designing though t of p roduct data management technique and integrates the draw ing design p roduct w ith data management of automobiles by secondary development w ith VB and A utoCAD2000 softw are1 To some extent, the system perform s the virtual design of automotive chassis and speeds the inquiry of the design and information in order to reduce designer′s labor intensity and raise designing efficiency. Key words: P roduct data management; Softw are development; Data base; A utomotive design
