摘要: 为满足空间光学系统用遮光罩结构大型化、复杂化、高收纳率的发展需求,提出一种大尺度异形可展开遮光罩薄膜结构。首先,根据光学系统遮光要求,研究了可展开遮光罩结构的总体设计方案。其次,基于Accordion(手风琴)折纸原理,开展了遮光罩薄膜结构折叠方案设计,建立了不规则多边形柱状折叠结构参数化数学模型。再次,采用ABAQUS仿真软件建立了薄膜结构展开过程仿真模型,分析了展开过程中应力的变化规律。最后,研制了缩比原理样机,并进行了展开功能试验。仿真及试验结果表明:所设计的遮光罩结构能够顺利完成展开动作,薄膜与可展开支撑机构无干涉,且展开过程无卡顿,薄膜未发生撕裂破坏现象。研究成果可为其他航天器遮光罩结构设计与研究提供一定的借鉴与参考。

Abstract: In order to meet the development needs of large-scale, lightweight and high storage rate of space optical system sunshield structure, a large-scale special-shaped deployable sunshield structure is proposed. Firstly, according to the shading requirements of the optical system, the overall design scheme of the deployable sunshield structure is studied. Secondly, based on the Accordion origami principle, the folding scheme design of the membrane structure of sunshield is carried out, and a parametric mathematical model of irregular polygonal columnar folding structure is established. Thirdly, the ABAQUS simulation software is used to establish the simulation model of the membrane structure deployable process, and the variation law of the stress during the deployable process is analyzed. Finally, a scale-down prototype is developed, and the deployment function test is carried out. The simulation and experimental results show that the designed sunshield structure can complete the deployment action successfully, the membrane has no interference with the deployable support mechanism, and there is no jam in the deployable process, and the membrane does not tear. The research results can provide certain reference for the structural design and research of other spacecraft sunshield.
