摘要: 以航空企业实际调研为基础,在传统飞机装配单元划分经验知识的指导下结合当前飞机数字化技术开展基于飞机三维模型的装配单元快速划分技术研究,提出以三维工艺分离面作为数字化装配单元划分依据,建立其建模算法和流程,并在此基础上进行装配单元构件快速识别和建模研究,建立装配单元快速识别和建模算法,从而实现装配单元的快速划分.这些技术和方法已在CATIA V5系统上得到初步开发和验证.Abstract: 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.
