| Abstract: | The Virtual assembly process planning in virtualenvironment is researched. The integrated system architecture isanalyzed. The three main problem of virtual assembly planning:virtual assembly, assembly sequence planning and assemblypath planning are analyzed. A product assembly model inassembly process planning is put forward,and the method ofhow to identify assembly constraint relations in the virtualenvironment is proposed,then method to constrain components'3D spatial movement under the constraint relations is realized.Based on these, a prototype system is established. Thus,a goodbackground for the further research of Virtual assemblyplanning is established. |
