摘要
分析了基于特征的虚拟装配产品信息模型,指出基于物理的虚拟装配产品信息模型的特征。在对STEP标准类库中的材料库进行扩展的基础之上,提出了以特征层次信息、信息类库信息和装配结构来描述基于物理的三层虚拟装配产品模型,建立了基于物理的虚拟装配产品信息模型。
This paper analyzes the feature-based virtual assembly product information model, and points out the features of virtual assembly product information model based on physics, and based on the extension of material class library in the STEP standard base, advances the physic-based three-tier virtual assembly product model which is described with the feature class information, class base information and assembly structure, and establishes a physicsbased virtual assembly product information model.
