张拉整体结构平衡状态的寻找

Finding of Equilibrium States of Tensegrity Systems

本文推导了张拉整体结构的找形分析公式，提出了得到平衡的预应力几何形状的计算方法，建立了结点的有限元基本方程和单元的刚度矩阵，既适于初始平衡态的结构，也适于初始非平衡态的结构。本方法有较高的数值精度，可作为设计张拉整体结构的基础理论和方法。

In this paper, the authors have derived the form-finding formulation of tensegrity systems andpresented the calculation method for finding Of balanced prestressed geometry. The fundamentalequations as well as element matrices have been derived. They can be applied not only to the initialbalanced geometry but also to the initial unbalanced geometry. The analytical model provided in thispaper are valid both for the fundamental theory and for the method of designing tensegrity domes withhigh accuracy.
