摘要：

为解决虚拟装配过程中产品模型信息的完备性和跟随性等问题，提出了面向装配过程的产品信息虚拟装配模型，该模型运用属性机制建立模型几何拓扑信息与非几何信息的映射关系，依据信息粒度采用树型框架结构构造信息的多层次表达结构，满足虚拟装配过程中产品信息表达完备、动态跟随和实时性要求。开发了虚拟装配建模系统，验证了实现技术的可行性。

Abstract:

In order to solve the problems such as completeness and following performance of product model information in process of virtual assembly, a process-oriented virtual assembly model for product information was proposed herein.It applied attribute frame to constitute the mapping among geometry topology information and non-geometry information，and based on information granularity，the structure of multi-layer representation for assembly model information was constructed by framework of tree structure.It can satisfy the requirements of representation completeness, dynamic following and real-time in virtual assembly．A modeling system was established and its feasibility was verified by research results.

Key words:

virtual assembly, product information, attribute frame, framework of tree structure
