Abstract:

To improve learning of structure design and training maintenance persons, a method for generating exploded view automatically was proposed based on synchronism release of parts geometric constraint relations. Part adjacency restriction relation matrix and restriction type matrix were built by defining part disassembly axial. Parts were stratifed according to the sequence of geometric constraint synchronism release, and sub-assembly was identified by defining rules. A method for parts isometric rate explosive separation form outside to inside was constructed. OBB(oriented bounding box) and FDH(fixed directions hulls) bounding boxes were used to realize the automatic generation of assembly component parts exploded view.

Key words: constraint release, exploded view, automation, bounding box
