Through analysis of Traditional CAD software modeling methods, combined with process planning requirements of intelligent virtual assembly, in the proposed semantic-based multi-level top-down model of virtual assembly. This paper proposes a semantic-based top-down model of multi-level virtual assembly.On this basis, the assembly semantic information extraction process is Focused analyzed, in the three-dimensional model data, non-geometric factors such as assorted features, assembly features, assembly engineering relations are extracted, and modeling is Established by Protégé ontology-based tool, the model is imported into the 3DVAPP(3D Virtual Assembly Process Planning) system to be verified, and Finally this paper implementated the assembly process planning applications such as intelligent parts identification, Provide a theoretical and practical basis for intelligent virtual assembly.

Aiming at the shortcomings of traditional assembly process design and immersive virtual assembly system, the architecture of Desktop Virtual Assembly System (DVAS) for interactive assembly process planning is presented. The key technologies such as data conversion and reconstruction of assembly models, assembly intention recognition and assembly control navigation are studied. The lightweight storage of assembly models’ data and the intelligent constraints recognition are realized. The problem of assembly operations resulted from the lack of immersion is solved by movement navigation. The algorithms were proposed and applied to the DVAS prototype, and an application case is studied to demonstrate the effectiveness of the system.

The assembly process planning of hull block is an important point in the study of manufacturing automation and computer integrated manufacturing system (CIMS), which will influence the construction period and quality in shipbuilding negatively. Based on the assembly level model, this paper presents a new design of assembly process planning for hull block. With the improved disassembly method, we can get the reasonable planning of assembly sequence. At last, the whole assembly process was simulated based on DELMIA software. The results show that the study will be instructive and meaningful to the assembly of hull block.
