摘要:
针对大口径和超大口径天线的刚度随其口径增大逐渐减弱的问题,该文设计了双环可展开天线桁架机构。分析了该机构的基本展开单元和机理,推导了可展开条件公式。在单环基础上,推导出双环可展桁架的约束方程;基于广义逆矩阵方法建立双环可展桁架的运动学基本方程,并进行双环可展桁架的运动学仿真。将同口径下单环和双环可展开天线桁架进行动力学对比分析,发现双环可展桁架的刚度比同口径单环可展桁架明显增强。采用设计制作的2 m 原理样机缩比模型验证了双环可展开天线桁架的可展开性,对2m 模型进行的动力学测试验证了分析结果的正确性。
Abstract:
In view of that the stiffness of the antennas becomes weakened sharply with thedevelopment of large caliber and very-extra-large caliber antennas, the deplogable double-ringantenna truss is designed. The basic deployable elements and mechanism are researched and the de-ployable condition equation is proposed here. Kinematics basic equations of a double-ring truss areestablished by the generalized inverse method. Constraint equations are established based on thesingle-ring antenna,and the numerical kinematics simulation of the double-ring deployable truss iscarried out. For large caliber antennas with the same caliber, the stiffness of the double-ringdeployable truss is obviously stronger than that of the common single-ring deployable truss. The 2 msize shrinkage ratio model is designed and deployed,and the dynamic experiment verifies that thedouble-ring antenna truss is deployable.
