摘要
本文阐述了张拉整体结构的组成和形式 ,并通过奇异值分解法对张拉整体结构的单元体进行了体系分析 ,证明文中所给的单元体是具有一阶无穷小机构的几何稳定体系。文中以平板型张拉整体结构为例研究了张拉整体结构的工作机理 ,分析了初始预应力与结构刚度的关系 。
In this paper, the structural composing and form of Tensegrity structures are introduced, the structural mechanism for the unit of Tesegrity is analyzed by using the SVD method, and the unit is proved to be a first order infinitesimal mechanism as result. The affinity between structural stiffness and initial pre stress is made a research with the example of plane Tensegrity. Finally, some useful conclusions are obtained. [
