空间薄膜天线索膜结构建模与形状优化
Cable-membrane modeling and shape optimization of the space membrane antenna
摘要
Abstract
A method about boundary modeling and shape optimization of the cable-membrane structure in the space planar membrane antenna is proposed.First,based on the characteristics of sliding between the cable and the membrane when the structure is tensioned,a method of the nonlinear finite element modeling is proposed.Second,the boundary of the cable-membrane structure is modeled by B-spline curves,and the design variables are displacements of the control points of the curve for this optimization problem. The shape optimization of the membrane with an arbitrary initial boundary is realized by optimizing the deviation between the actual stress and the engineering reference stress.Finally, the effectiveness of the proposed methods are illustrated by numerical examples and experimental verification.关键词
