Abstract:MBD-based assembly process of three-dimensional digital design is not only an new discipline in aircraft digital manufacture , but also the future aircraft design trends. The technology completes the jobs of division of the three-dimensional process splice surface based on MBD, BOM reconstruction, process simulation and establishment of three-dimensional assembly order by customization and multi-system integration of process design, process simulation software, such as DELMIA, 3DVIA Composer, CAPP, and so on. The technology transfers the completed process design information to production scene by product management system, the technology opens technology roadmap from the MBD-based product design, process design to on-site visualization assembly.
