太阳帆结构分析

太阳帆是人类向太空发射的一种宇宙探测器。本文推导建立了太阳帆结构分析的理论方程组；利用数值计算方法进行了全结构分析；采用罚函数法，确定了满足各种技术条件下的转速及辐条长度之间的可用范围；同时，在引入某些假设的前提下，得出了方程组的近似理论解。它们为太阳帆强度分析、结构形状保持能力提供了论理基础，也为太阳帆的设计提供了依据。本文最后提供了某实际发射的太阳帆结构的分析结果。本文的分析手段可作为大型柔性结构分析的参考

STRUCTURAL ANALYSIS OF SOLAR SAIL

Solar sail is a kind of space probe sended into outer space by mankind. The theoretical equation system of structural analysis on solar sail is given in this paper. The whole structure is studied with the help of numerical calculation method. Then the advisable ranges of rotating velocity and the length of stripes are determined by using SUMT when all technical conditions are satisfied. Meantime, some assumptions are recommended and the approximate theoretical solution of the equation system is obtained. These theories and methods provide theoretical foundations for the strength calculation and the ability of formmaintaining of the structure, and this provides basis for the design of solar sail, too. Finally the calculation results of an actual launched solar sail are given in this paper. The method used in this paper can be a reference to the structural analysis of super flexible structures.
