基于PLIB/STEP标准的集成产品数据模型的研究

Research on of Integrated Product Data Model Based on PLIB and STEP

STEP(ISO10 30 3)标准对产品全生命周期信息进行规范化描述 ,是产品信息交换的基础 ,但缺乏高层次的语义描述 . PL IB(零件库标准 ,ISO135 84)通过总模型、功能模型和功能视图模型类及其结构来表示产品设计原理和多域多级别视图显示 .结合 PL IB/ STEP的特点 ,提出了集成产品模型及信息共享的机制 .

STEP (ISO 10303) describs product model information for life cycle engineering. It is the basis for the exchange of product data, but lacks advanced semantic expression. PLIB (Parts Library, ISO13584) expresses product model information by General Model, Functional Model, Functional View Model and Representation Category. It provides the capabilities to describe product information multi\|expert and multi\|level perspective. Based on PLIB and STEP, the integrated product model is studied, and the mechanism of product information sharing is also provided.
