Abstract:
The Virtual
assembly process planning in virtual environment is researched. The
integrated system architecture is analyzed. The three main problem of
virtual assembly planning: virtual assembly, assembly sequence planning
and assembly path planning are analyzed. A product assembly model in
assembly process planning is put forward, and the method of how to
identify assembly constraint relations in the virtual environment 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 good background for the further research of
Virtual assembly planning is established.
Key words: Virtual
