| Virtual assembly is one of application of virtual reality technology in the field of factory, assembly is the last step among product production, the technology of virtual assembly by approaching of researchers in home and abroad has made great progress,This subject uses Planetary gear reducer for Engineering machinery of yiqun company,the primary research on: modeling, assembly process, conflict, virtual assembly system.First of all,master the structure, function of the planetary reducer and where application it.Second, we should understand the relationship of assembling components, in the soft of solidworks select suitable style of modeling, such as, based on featured, based on geartrax, based on toolbox, according of the feature of parts, for assembling used the style of assembly from down to up, accomplished total assembly planetary reducer after the partial assembly, meanwhile, check whether there is space interference phenomenon between parts,in the static and dynamic intervene, to ensure product assembly,after import the product into 3dsmax to setup material and rendering, for creating virtual assembly system.So far, the problem of assembly process in the presence of planetary reducer should be analyzed, make use of hierarchical cut-set method, which solved assembly process, to calculate reducer assemble sequence and optimize one.The last, develop the planetary reducer virtual assembly system in the soft of virtools, including operation introduction and Assembly demonstration.Research on this subject have some value to manufacturing enterprise,on the one hand, one reason that without prototype so it can save much capacity,riser production rate, improve the production of assemble quality, on the other hand it enhances company compete in the fiercely nation and abroad marketplace, while, the designer also amend and enhance the product when they find it has some drawback in the virtual assembly system. it also offer a sample for solving other products and industry matters. |
