摘　　要：展开机构及展开锁紧较链用于完成可展开天线的展开和锁定,其方案设计直接影响天线的展开可靠性和展开锁定后的形面精度,是天线设计中的重要环节。本文针对星载板状反射面天线,以微间隙展开锁紧铰链及展开机构的设计为核心,对展开机构进行了动力学仿真分析和主要零部件的结构力学分析,分析验证展开机构方案的可行性。The deployment mechanism and the deployment of the locking hinge are used to complete the deployment and locking of the deployable antenna.The design of the solution directly affects the deployment reliability of the antenna and the accuracy of the profile after the locking is completed,which is an important link in the antenna design.In this paper,the star-shaped slab-shaped reflector antenna is based on the micro-gap deployment of the locking hinge and the deployment mechanism.The dynamic analysis of the deployment mechanism and the structural mechanics analysis of the main components are carried out to verify the feasibility of the deployment scheme.
