The Application of Three-Dimensional Digital Technology in Aircraft Assembly Process Design System

3D digital assembly process design technology is the combination of the three dimensions and information with the new software technology in traditional process design. This article is based on an aviation manufacturing enterprises priority to the realization of the whole assembly process design, simulation and verification business process, which mainly with Dassault Companys DELMIA and 3DVIA Composer platform. In this paper, some process design thinking and methods are introduced to the aircraft product process about the separation technology division, BOM reconstruction, process simulation, 3d assembly instruction compiling, and the like. It also introduces some application methods of system integration.
