Rapid partitioning of an aircraft 3D model into its assembly cells

By the investigation of practical production the methods of aircraft assembly cell partition in the field of home aviation were wildly collected and deeply known about. Refer to the literature and information about the technique of aircraft assembly, the traditional experiences and knowledge of aircraft assembly cell partition were sorted out in detail and deeply analyzed. The digital technique of aircraft assembly cell rapid partition was investigated on 3D modeling of aircraft. The 3D process split surface which becomes the foundation for digital assembly cell partition was put forward and defined, and its modeling arithmetic was constructed respectably. Then based on the 3D process split surface, the methods of the component recognition and modeling for an assembly cell were put forward. The rules of the component recognition were established accordingly and the modeling arithmetic of new assembly cell was constructed. The proposed techniques were initially developed and verified on the CATIA V5 system.
