Research on Technology of Process-Oriented Virtual Assembly Modeling for Product Information
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 is proposed in this paper. It applies attribute frame to constitute the mapping of geometry topology information and non-geometry information, and basis for information granularity, the structure of multi-layer representation for assembly model information is constructed by framework of tree structure. It can satisfy the requirements of representation completeness, dynamic following and real-time requirements in virtual assembly. A modeling system was established and its feasibility was verified by research result.
