面向制造的通用飞机数字化设计方法研究

Digital Design Method of General-purpose Plane Aimed at Manufacturing

为提高装配图纸对生产的可指导性,实现总装物料与图纸的层级对应,同时减少详细设计阶段各专业的冲突,对面向制造的通用飞机数字化设计方法进行了研究。结合生产工艺流程进行总体方案设计,确定总体参数;以装配流程为建模结构,在按需求配置的协同设计平台中搭建总体骨架,进而开展详细三维建模工作。通过实际机型的三维建模证明,此种建模方式下设计过程中的模型冲突得到了即时解决,各分工位设计实时关联,设计图纸可直接指导生产装配,大幅度缩短了研发周期。

In order to improve the guidance of the drawing to production and achieve the correspondence between MBOM and the drawings, a method of digital design for general-purpose aircraft aimed at manufacturing has been researched while reducing the conflicts of each professional field during detailed design at the same time. The general scheme was designed combined with production process, and the general parameters were defined at this stage. The structure of 3 D model was based on assembly process and the skeleton was created based on the demand-orien- ted collaborative design platform. Thus the 3 D models was designed. The test on a real type of aircraft shows that based on the 3D modeling, the conflicts during design were solved immediately, the designs between several stations were associated immediately, the production was guided by drawings directly and the development period of the aircraft was shortened significantly.
