汽车车身设计CAD/CAE信息集成系统中Oracle数据库的设计研究

Study on Oracle Database Design in Integrate CAD/CAE System of Car-body Design

论文通过现代汽车车身工程中的CAD用户、CAE用户、管理人员对CAD CAE信息集成系统数据需求的分析,从面向车身工程的现实世界出发进行数据库概念设计、逻辑设计和物理设计,实现了汽车车身设计CAD CAE信息系统数据库从现实世界模型向数据库逻辑模型的转化及实现。

This article, based on the analysis of users′ demands (such as CAD users′, CAE users′, manager′) for database of car-body design CAD/CAE system, beginning from the real world of car-body design engineering, studies the database conceptual design, logical design and storage systems design, to realize the database change from real world model to logical and storage model. Built on Oracle8, the database for car-body CAD/CAE system contains two main elements. One is an exact virtual geometric model for designer to develop new bodywork expediently. The other main element is dynamics models, which are important to analyze a new component.
