摘要/Abstract

摘要： 随着人类进入大宇航时代，对空间天线提出了大口径、轻质量与高收纳比的要求。针对大口径AstroMesh网状天线收拢高度难以满足火箭整流罩尺寸要求的问题，提出了一种索穹顶网状可展开天线创新设计方案。通过引入由受压杆、环索与斜索组成的索穹顶结构，实现天线下索网分环设计，缩短了与下索网相连的桁架竖杆长度，从而降低了天线整体收拢高度。通过16 m与100 m两种典型口径天线设计参数对比，结果显示该创新方案不仅破解了AstroMesh网状天线收拢高度高的问题，而且具有低面密度、结构简单的优点。设计并制作了1 m口径索穹顶网状可展开天线原理样机，开展了面形精度与展开过程测试实验，验证了设计方案的有效性。所提创新设计方案为未来百米口径网状可展开天线结构设计提供了新思路。

Abstract: With the entry of human beings into the great space era, the requirements of large-diameter, light-weight and high storage ratio are put forward for space antennas. In order to solve the problem that the stowed height of large-diameter AstroMesh antennas is difficult to meet the size requirements of rocket fairing, an innovative design of the deployable mesh reflector antennas with cable dome structure is proposed. By introducing a cable dome structure that consists of compression rods, ring cables and oblique cables, the division design of rear cable-net is realized. In this case, the length of batten connected to rear cable-net is shortened, and the overall stowed height of reflector antennas is reduced. By comparing the design parameters of two typical antennas with 16 m and 100 m apertures, the results show that the innovative design not only solves the problem of the high stowed height of AstroMesh antennas, but also has the advantages of low areal density and simple structure. A prototype of 1 m diameter deployable mesh reflector antenna is designed and fabricated, and both surface accuracy and deployment process tests are carried out to verify the effectiveness of the design concept. The proposed innovative design provides a new idea for the structure design of 100 m diameter deployable mesh reflector antennas in the future.

Key words: cable dome structure, deployable mesh reflector antennas, prototype, stowed height
