摘要
本文导出了空间张拉杆系统平衡状态寻找的数值方法。采用矩阵分析法寻找系统的初始平衡状态，将修正的杆单元理论推广运用于系统任意工作平衡状态的寻找。分析中可考虑体系的弹性变形、内部机构和刚体运动。算例表明本文方法是精确和有效的。
In this paper the numerical method is proposed for finding the equilibrium states of prestressed spatial member systems. The initial state of systems is analyzed by the matrix method. The modified member theory is adopted to solve the working equilibrium states of systems. The elastic deformation, the inner mechanism and the rigid motion of systems can be properly considered. Numerical examples show that the method of this paper is accurate and effective.
