The Research On Naval Virtual Assembly Technological Optimization And Simulation

With the global and network's development of the manufacturing, virtual manufacturing technique becomes more important than ever. Virtual design, virtual manufacturing, virtual assembly etc. as 21 centuries of new manufacturing strategy have already attracted more and more attentions of universities, research institutes and enterprises, and these have become one of the key technologies in the new century of manufacturing.Assembly Technique Planning is the important content of Virtual Assembly, which have a profound meaning in enhancing the quality of product, reducing the price and shortening the period of produce. The paper is based on the Assembly Sequence Planning, and has the further research on virtual assembly models, assembly models and Assembly Sequence Planning.The paper expatiated the main contents of virtual assembly, basic flow and the key technologies. It proposed the assembly information models basing on structure of the former three dimension graphs. Associated with the extraction of sub-assembly and groups, assembly level tree, assembly relational graphs, it proposed delaminating assembly sequence cut-set method.Finally, focusing on double bottom of general cargo boat, this paper set up assembly sequences model and finished the simulation of the assembling process.The paper's virtual assembly is based on the CATIA environment; it hoped that though the discussion of this paper a naval virtual assembly environment could be founded which can be created parts, assembled, analyzed, and hoped that it can be linked with engineering projects and instructed the actual manufacture.
