【摘要】 空间充气结构具有折叠体积重量轻,展开结构可自由灵活设计的优势,尤其适合在空间可展开结构中应用。但是鉴于空间任务的高可靠性要求和空间发射的高成本现实,空间可展开结构的展开流程可靠性成为近年来的需对空间工程应用的研究重点之一。为了保证空间充气结构展开过程的可靠性,在研制的初期设计阶段和后期的原理样机试制阶段都需要有可靠的仿真计算能力支撑整个研制过程。首先介绍空间充气杆件及杆件与挂帆组合展开过程的数值仿真分析研究,通过单充气杆仿真计算对充气杆件的折叠方式进行了分析选择,通过杆件与挂帆组合展开过程仿真计算初步验证了展开结构设计的合理性和展开过程的可靠性。更多还原

【Abstract】 Because of the advantages of light weight, compact volume and high design flexibility, inflatable structures are especially suitable for space applications. However, as to the space tasks’ characteristics of high reliability and high cost, the reliability of the inflatable structures’ deployment process becomes the recent research emphasis of space engineering. The numerical simulation of the deployment process becomes the supporting capability of the whole development process including the design of the initial stage and the prototype fabrication of later stage. The simulations of single space air-beam and inflatable structures of beams with their sails are conducted. With the single beam deployment simulation, the optimal beam’s folding pattern is selected. With the composite structure simulation, the reliability of the structure design is initially verified.更多还原
