可折叠单元在张弦桁架结构中的初探

Application of Deployable Elements to Truss String Structure

介绍了几种常见的可折卺结构．例如可折叠空间网格结构、可折叠桁架结构、可折叠门。通过改进常见的剪切杆单元．结合可折叠门．形成了一种新型剪切杆单元体系，将它应用于张弦桁架结构．最后提出了可折叠张弦桁架结构。介绍了可折叠张弦桁架结构的主要组成部分．如可折叠单元、连接接头等．它们将是以后实验研究和实际应用的基础。对可折叠张弦桁架结构进行了可行性分析。结果表明．无论屋顶关闭或开启．可折叠张弦桁架结构的横向稳定性都能够保证。从而得出：可折叠张弦桁架结构是科学合理的。

Several common deployable structures such as deployable spatial grid structures, deployable trusses and deployable door were introduced, inspired by the deployable door. By improving the common shearing lever elements, a new style shearing lever element system was formed, and which was applied to the truss string structure, in the end, the deployable truss string structure was put forward. The main fabrication of the deployable truss string structure include deployable elements, connecting joints and so on. which is the foundation of the experimental research and practical application in future. The feasibility analysis of the deployable truss string structure was carried out. The results indicate, no matter when the roof is closed or opened, the lateral stability of the deployable truss string structure can be ensured. The deployable truss string structure system is scientific and reasonable.
