摘要
以理想桁架节点笛卡尔坐标为未知量 ,全面建立了复杂桁架结构的几何约束方程 ,并推导出相应的几何约束 Jacobi矩阵 ,建立了空间展开桁架结构展开过程分析的理论与方法 ,系统地分析了机构特性 ,阐明了展开过程的力学本质特点 。
Geometrically constrained equations are formulated completely, and relevant Jacobi matrices are derived with Cartesian coordinates of idealized truss joint as variables. Theory and analysis approachs of the deployment process, which are suitable for deployable space trusses, have been developed. Statically determination/indetermination is analyzed systematically. Essential mechanics characteristic is illustrated for quasi\|static deployment analysis. Stabilization condition and/or objection functions are presented intently. Numerical examples prove that the method is correct and effective.
