By making full use of the idea of product data management (PDM) technology, taking automobile product design as an example, on the basis of establishing parts graphics library and chassis parameter database, secondary development is carried out through VB and AutoCAD2000 software, integrating drawing design and data management. To a certain extent, the virtual design of automobile chassis is realized, and automobile design and data query can be carried out quickly and efficiently, thereby reducing the labor intensity of designers and improving design efficiency. Key words: Product data management; Software development; Data base; Automotive design Abstract: Taking the design of automotive product as an example and on the basis of establish ing the components library and data base of the chassis parameters, this article makes full use of the designing though t of product data management technique and integrates the drawing design product with data management of automobiles by secondarydevelopment with VB and AutoCAD2000 software1 To some extent, the system perform s the virtual design of automotive chassis and speeds up the inquiry of the design and information in order to reduce designer′s labor intensity and raise designing efficiency.Key words: Product data management; Software development; Data base; Automotive design
