| 摘 要： | 本文以三块各向正交异性矩形板组成的卫星帆板为研究对象,首次利用半解析方法研究了其横向弯曲的问题。就板间连接处复杂的边界条件,提出了与之对应的挠度函数形式。在此基础上采用相同形式的挠度函数求出了帆板在各种横向外载荷作用下的挠度,为解决多板连接结构的弯曲问题提供了一种有别于以往数值方法的新思路。

| Abstract: | In this paper, the bending of solar array under various lateral forces is studying by semi-analytic method for the first time. The solar array consists of three orthotropic rectangular plates. New functions are proposed as the lateral deflections satisfying complex boundary condition. The bending with an arbitrary load is worked out by a unite lateral deflection. The numerical tests show that the method and the lateral deflections selected in the paper are reasonable. |
