飞机装配工序的可视化建模及仿真

Visualized Modeling and Simulation of Aircraft Assembly Process

针对目前国内外飞机装配工序设计技术研究中存在问题,从新的角度提出基于产品预装配功能自动生成飞机装配工序的方法。通过分析飞机装配工序的组成及特点,建立其数字化模型;利用产品CAD系统中"装配设计"功能开展飞机交互预装配,并从中提取相关装配工序信息,自动生成装配工序;设计和开发算法,将产品装配工序转化为宏指令代码,运行此代码可实现飞机装配过程的动态仿真。结合某飞机垂直尾翼的总装,验证了方法的可行。

Facing to the problems in the aircraft assembly at present, a preliminary assembling model is established first based on conventional experience. Then using the ＂Assembly Design＂ functions of CAD system, the preassembling process is interactively accomplished and the whole procedure with detailed information about the moving path and locating datum of parts etc, is recorded in the form of macro commands of the CAD system. These two files are merged to realize the automatic generation of assembly process and macro commands to drive the assembly simulation and verification. The assembly process planning and assembling simulation of the vertical tail of an aircraft is used to validate the proposed approach.
