摘要
通过介绍压力容器ＣＡＤ系统（ＰＶＣＡＤ）的数据管理机制，旨在给出一种面向工程设计的产品数据管理模式．这种模式能够使系统实现对通常工程设计所需的产品数据进行有效地管理和自动地访问．为此，较详细地说明了系统中产品数据模型的数据分类、表达方式、数据结构及其实现方法．
This paper aims at providing a product data management method oriented engineering design by describing its implementation in the Pressure Vessel CAD system(PVCAD). By this method,a CAD system can efficiently manage and automaticly visit those product data in normal engineering design.It comprehensively describes the data classification,expressive form,data structure and implementation method for the model of product data in the system.
