摘要
环形反射器单元杆件之间的支反力是单元展开过程中的主要动力源。文章介绍了环形反射器单元的展开原理和结构形式,分别对反射器单元的斜杆和横杆进行了基于静力平衡的受力分析,推导了杆件支反力关于结构参数及展开角的表达式,并进行了计算,得出了杆件支反力随展开角的变化曲线。
Support reaction force between poles is the main source of power of deployment between units of a ring reflector.The principle of deployment and structure of unit of ring-deployable reflector are introduced.The force analysis based on static balance of diagonal poles and vertical poles of unit of the ring reflector is conducted separately,and then support reaction force functions on structural parameters and deployment angle are derived.Further,the functions are calculated,and the curves are gotten of support reaction force vs.deployment angle.
