飞机型架设计中的空间角度计算

Solid Angle Calculations in Designing the Assembly Jigs

本文根据投影几何的基本原理和角度之间的基本关系,提出建立基本单元体的方法,共推导出7个基本公式和25个导出公式。从而简化了飞机型架设计过程中的空间角度计算,压缩了公式的数量。

In the light of the basic principles of projective geometry and the basic rela- tions between angles,this article presents a method of forming elementary units,and deduces seven basic formalas and twenty five of their derivatives,thus simplifying solid angle calcula- tions and reducing the number of formulas in designing plane assembly jigs.
