摘要
分析了集成信息CAD系统中要解决的产品模型信息描述问题。基于STEP标准和IDEF产品建模方法，提出了基于功能层的产品信息建模和产品信息模型的三层结构：功能层、零部件层和构造层。以工程中业已标准化的滚动轴承为对象建立了基于STEP标准的产品功能信息EXPRESS描述模型，为集成信息CAD系统的信息集成中性环境的建立提供了基础。
The issues on description of product model information in integrated information CAD system is analyzed inthis paper. Based on STEP standard and IDEF method,function model of product model information and its structureswith three layers (i. e. function layer,generic part layer,generic structure layer) are built. According layer structure offunction model and STFEP standard,the function information model of rolling bearing was constructed and expressed. Theworks provide foundation on building neutral context for representation and exchange of information in integrated information CAD system.
