摘要:

利用光纤光栅传感头获取板面的空间曲率信息,提出基于递推法的三维太阳能帆板的面型重构方法.以太阳能帆板的一个单元为研究对象,着重分析了太阳能帆板的单元面型重构的几何模型的建立,以及边界约束和曲面中曲率相等的数学表达.最后将单元面型重构的几何模型转化为求解多元非线性方程组问题,并进行数值仿真,从而为拼接整个曲面提供一个方法.

Abstract:

This paper presents a recursive method of reconstruction of 3D curved surface by using spatial curvature obtained from fiber Bragg grating (FBG) sensors. A geometry model of solar array surface reconstruction is introduced. Expression of boundary constraints and equivalents of the surface’s middle curvature are presented. The geometry model of surface reconstruction is then translated into systems of nonlinear multivariable equations, and illustrated by numerical simulation. This provides a method for formation of the entire-surface.

Key words: surface reconstruction; systems of nonlinear multivariable equations; spatial curvature; fiber Bragg grating (FBG)
