摘要
文中较为系统地介绍了国内外大口径星载可展开天线研究的现状及其未来发展趋势,内容涉及网状、薄膜、微电子机械、固面、充气等不同类型天线。对应用广泛的大型索网天线,阐述了数字化建模、网状找形找态、多态动力优化、多柔体动力学分析与展开过程控制、展开可靠性分析、在轨热分析与控制、形面调整与测试、机-电-热场耦合建模与电性能分析等模型建立、分析与设计方法以及针对星载可展开天线分析与设计的知识型设计软件与综合设计支撑平台等。此外,对正在研制与在轨服役的星载天线也作了简单介绍。
The state-of-the-art and development trend of the large space-borne deployable antennas are presented in this paper. Almost all kinds of deployable antennas are included such as the mesh reflector with cable net, the membrane reflector, the antenna with micro-electronic-mechanical structures （MEMS）, the solid reflector, the inflatable antenna and so on. The model establishment ＆ analysis and design methods are described, such as digital modeling, form finding, analysis of flexible structures, deployment procedure control, reliability analysis of deploy- ment process, thermo analysis and control in the orbit, measurement and adjustment, the integration with mechani- cal, electromagnetic and thermo technologies, and the computer software platform for space-borne antenna analysis and design is also introduced, particularly for the mesh reflector with cable net. In addition, some other deployable antennas under development and in service in space are introduced briefly.
