摘　　要：制备能可靠收展的高收纳比、动力学性能优良的支撑结构是大型星载天线技术发展的关键需求之一。针对环形天线反射器的支撑结构提出改进方案,通过设计支撑桁架的接头结构使其适用于多种单胞数目,为环形天线支撑桁架的地面动力学实验提供便利。首先对支撑桁架进行三维建模及运动仿真,验证方案的可行性,然后分别研制出了可展桁架实物模型,最后进行了支撑结构展开实验,验证了可展支撑桁架结构设计的可行性。One of the key requirements for the development of large-scale satellite antenna technology is to prepare support structures with high storage ratio and excellent dynamic performance that can be reliably retracted.this paper proposes an improvement plan for the support structure of the circular antenna reflector,and designs the joint structure of the support truss to make it suitable for various unit cell numbers,providing convenience for ground dynamics experiments of the circular antenna support truss.Firstly,three-dimensional modeling and motion simulation are conducted on the support truss to verify the feasibility of the scheme;then,physical models of the deployable truss are developed;finally,support structure deployment experiments are conducted to verify the feasibility of the design of the deployable support truss structure.
