Abstract

An integrated database architecture is presented to support the diverse requirements of a CAD environment. The resulting CAD system consists of a design representation database, an existing-design database, and a parts catalog database. The design representation database stores and manages designs currently being developed. The existing-design database and the parts catalog database serve as suggestion systems. The first suggestion system helps the designer by recommending an existing design that closely satisfies the input specifications. In the second suggestion system, the user provides an incomplete component specification and the system suggests a set of standard components that fit these descriptions. A structure-function CAD modeling paradigm is used to represent designs, to perform simulations, and to let designs evolve over time. The structural information represents the physical or the logical aspects of the design, whereas the functional information represents the behavioral aspects of the design.<>

数据库支持工程CAD和仿真

提出了一种集成的数据库体系结构，以支持CAD环境的多种需求。所得到的CAD系统由设计表示数据库、现有设计数据库和零件目录数据库组成。设计表示数据库存储和管理当前正在开发的设计。现有设计数据库和零件目录数据库作为建议系统。第一个建议系统通过推荐一个非常符合输入规范的现有设计来帮助设计师。在第二个建议系统中，用户提供一个不完整的组件规范，系统建议一组符合这些描述的标准组件。结构-功能CAD建模范例用于表示设计，执行仿真，并使设计随时间发展。结构信息代表设计的物理或逻辑方面，而功能信息代表设计的行为方面
