摘要
提出了一种星形张拉整体可展结构.该结构基于张拉整体单元转化的星形张拉整体结构构建,具有中心单一构件驱动即可实现结构折展的特点.针对星形张拉整体可展结构的工作原理、驱动原理、中心构件长度对结构参数和力学参数的影响等,通过理论分析和仿真研究,对其折展可行性进行了分析验证.
A star-tensegrity deployable structure is presented. It is formed through transforming the star tensegrity structure and can be driven by a central member to complete folding and deploying. Firstly, based on the tensegrity unit, the star-tensegrity structure is presented and the scheme for the star-tensegrity deployable structure is investigated. Then how to drive it is discussed and determined. Finally, the influence of the central member length on the structural and force parameters is analyzed. Through theoretical analysis and simulation, the feasibility for folding and deploying of the star-tensegrity deployable structure is checked and verified. The results show that a feasible star-tensegrity deployable structure is obtained.
