摘要
设计了一种用于空间可展抛物面天线的能量节点机构 ,并分析其展开机理 ,对杆件及其端部的扭簧组成的宏单元的缩减刚度矩阵进行了讨论 .结果表明 ,在结构体系中设置能量节点可显著改善结构的共振性能 ,证明该设计是可靠。
A kind of energy\|loaded joint used for deployable space structures is proposed and designed, and its deploying mechanics is also studied. The curtail rigid matrix of macrocell which is composed of the rod and its torsiomal springs has been analyzed. It has been shown that the resonant behaviour of structure was significantly improved by introducing the energy\|loaded joints into it. It's proved that this design is reliable and feasible.
