2011年9月,天宫一号目标飞行器发射升空,于2011年11月、2012年6月和2013年6月与3艘载人飞船完成3次交会对接,航天员两次进入实验舱生活和工作.实验舱是目前国内首个在轨工作2年以上的载人密封舱,该密封舱首次采用整体壁板式结构.本文分析了长寿命载人密封舱结构设计约束条件,通过不同结构形式的比较,提出了密封舱采用整体壁板结构,介绍了壁板结构设计准则和研究内容.该项设计技术的突破为我国未来大型长寿命载人航天器,尤其是载人空间站结构奠定了基础.
In September 2011, the Tiangong-1 target aircraft was launched and launched. Three rendezvous points were completed with three manned spacecraft in November 2011, June 2012 and June 2013, and the astronauts entered the experimental module twice The experiment chamber is currently the first manned seal chamber in China that has been in operation for more than two years and the first time adopts the integral wall plate structure.This paper analyzes the structural design constraints of the long life manned capsule, In comparison, the overall structure of the balusting chamber is proposed, and the design criteria and research contents of the siding are introduced.The breakthrough of this design technique lays the foundation for the future large-scale manned spacecraft in China, especially the manned space station structure.
