Abstract:
Technology of movement and knowledge guidance in virtual
assembly is presented. The designer can move the mechanical part
precisely under the movement guidance. The movement guidance is
implemented based on constraint recognition and assembly degree
of freedom analysis. A multi-hierarchy knowledge base is built
to represent the assembly knowledge and information. The virtual
assembly system judges the requirement of the designer based on
the context of design task and searches for the useful knowledge
and information, which can be provided to the designer in a
natural way.
