Wrinkle analysis of a space planar film reflect-array
Abstract：The presence of wrinkles in a membrane is the main factor that induces surface errors on space planar film reflect arrays. Based on the commercial finite element (FE) package ABAQUS, a numerical procedure for membrane wrinkle analysis was set up, and used to analyze a square planar film reflect-array under pure shear force to evaluate its induced wrinkle characteristics. First, the effect of shear force on the wrinkle pattern of the array was studied and validated by experiment. Second, the effect of prestress was studied. When the prestress increases, the quantity of the wrinkles increases, and the amplitude of the wrinkles decreases. Third, the influence of the boundary conditions was investigated. A frame side edge structure has a relatively smooth surface, but also relatively high stress. Finally, the behavior of a joint seam was analyzed. The results indicate that a joint band has a significant influence on the wrinkle pattern of the membrane. 作者： Author： Wei-wei XIAO Wu-jun CHEN Gong-yi FU 作者单位： Space Structures Research Centre, Shanghai Jiao Tong University, Shanghai 200030, China 期 刊： 浙江大学学报（英文版）（A辑：应用物理和工程） ISTICEISCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年，卷(期)： 2011, 12(1) 分类号： V214 O312 Keywords： Space planar film reflect-array Wrinkle analysis Joint seam 机标分类号： TH1 U21 机标关键词： shear force boundary conditions influence finite element significant array structure quantity analysis results errors ABAQUS frame Based main high set 基金项目： the National Natural Science Foundation of China【Wrinkle analysis of a space planar f】相关文章：
