Static analysis of synchronism deployable antenna

Abstract：A 3D synchronism deployable antenna was designed, analyzed, and manufactured by our research group. This antenna consists oftetrahedral elements from central element. Because there are springs at the ends of some of the rods, spider joints are applied. For analysis purpose, the structure is simplified and modelled by using 2D beam elements that have no bending stiffness. Displacement vectors are defined to include two translational displacements and one torsional displacement. The stiffness matrix derived by this method is relatively simple and well defined. The analysis results generated by using software developed by our research group agreed very well with available test data. 作者： Author： GUAN Fu-ling[1]  SHOU Jian-jun[1]  HOU Guo-yong[1]  ZHANG Jing-jie[2] 作者單位： Department of Civil Engeering, Zhejiang University, Hangzhou 310027, ChinaChongqing Research Institute of Building Science, Chongqing 400015, China 期 刊： 浙江大學(xué)學(xué)報(bào)A（英文版）   ISTICEISCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年，卷(期)： 2006, 7(8) 分類號(hào)： V414.2 Keywords： Space deployable structures    Analysis design    Reflector antenna    機(jī)標(biāo)分類號(hào)： TU3 U66 機(jī)標(biāo)關(guān)鍵詞： bending stiffness    stiffness matrix    beam elements    test data 基金項(xiàng)目： 國家高技術(shù)研究發(fā)展計(jì)劃(863計(jì)劃) Static analysis of synchronism deployable antenna[期刊論文]  浙江大學(xué)學(xué)報(bào)A（英文版） --2006, 7(8)A 3D synchronism deployable antenna was designed, analyzed, and manufactured by our research group.
