太阳翼基板的构型分析

针对太阳翼基板构型设计方法缺乏系统性和普适性问题,提出太阳翼基板构型的基本几何模型——可展曲面.利用类比的方法,将可展曲面上的直母线当作基板间的转动副,将直母线之间的曲面当作基板,建立可展曲面与基板构型之间的对应关系.从几何学和机构构型的角度研究太阳翼基板的折展原理,建立不同基板构型的几何特征约束方程.阐述太阳翼基板构型基本组成单元的概念并找到各基本单元,对现有的太阳翼基板构型进行分类,并对不同的构型进行分析,验证了可展曲面与基板构型的对应关系.对新型太阳翼基板构型进行分析,并建立了对应的几何模型.

Configuration analysis of solar wing panels

To enhance the systematization and universality of solar wing panels'' design theories and methods, a geometric model is proposed to describe the relationships between developable surface and panels'' configuration. Using the analogy method, the straight generatrix of developable surface is regarded as revolute joint between two panels while the developable surface between straight generatrices as the panel. The unfolding principles of solar wing panels are expounded from the perspectives of geometry and mechanical configuration, the constraint equations of geometric features in the different panels'' configurations are established. The concept of basic component of developable solar wing panels is elaborated and the basic components are found, which is helpful for its innovative design. The existing solar wing panels'' configurations are classified and analyzed to demonstrate the relationships between developable surfaces and panels, the geometric model of a new panels'' configuration is built by configuration analysis at last.
