空间可展开天线是现代卫星通信、地球观测、深空探测等航天和国防领域的关键设备之一，现正朝着高频段、高增益、高精度与大口径的方向发展。剪式铰可展开天线在周边桁架天线的基础上，结合张拉整体结构的特性设计而成，使用弹簧驱动的剪式铰结构形成自驱动展开结构。对其结构设计原理、不同口径下形面精度以及展开过程运动性能的研究和分析表明，该天线收拢体积小、形面精度高、质量轻，可用于制作大口径、高精度的空间可展开天线。

Space deployable antennas are indispensable for future advanced satellite communication, earth observation and deep space exploration systems. The tendency of deployable antennas is large aperture, higher gain and frequency. On the basis of hoop truss deployable antennas, the self-driven deployable structure with scissor-like hinges is designed by in-corporating with tensegrity structure properties. The results of analysis on structure design principles, surface accuracy of different apertures and deployment motion performance show that the self-driven deployable structure with scissor-like hinges can be applied to space deployable antennas with large aperture and higher precision due to the smaller folded volume, high-er surface accuracy and light weight.
