摘要
在总结国内外充气式可展结构研究现状的基础上,提出了圆柱形充气式索膜结构的构形,并重点对圆柱形充气式索膜结构进行了折叠展开仿真分析。采用LS-DYNA软件对Z字形折叠和卷曲折叠的圆柱形膜和索膜结构进行了充气展开过程的仿真,并比较不同折叠方式的充气展开过程,探讨充气速率大小对结构稳定性的影响。
On the basis of summarizing the previous researches, a type of cylindrical inflatable cable-membrane structures is proposed. Deployment process is presented. Then, the model of Z-shaped fold and spiral fold of cylindrical inflatable membrane structures and cable-membrane structures are established using LS-DYNA. Different folding manners are compared, and the effect of inflation rate on the structural stability is considered.
