With the development of science and technology and incessant exploring outer space , the deployable structures are being used widely masts are basic deployable structures , being a effective supporting structures , masts are often used for separating electronic instruments to reduce interference or supporting other structures such as deployable antennas , solar arrays , telescope , outer space manipulator , outer space flat roof 随着科学技术的发展和人类对太空的探索不断深入,可展开结构越来越广泛的得到应用。伸展臂是最基本的可展结构,作为一种有效的支撑结构,可以作为大型可展开天线、太阳帆和望远镜的支撑背架、太空机械手以及空间平台等,已经得到了广泛的应用。
Following the developing of the aeronautical technology , higher request was brought forward to deployable antenna on satellites from every relative field . a lot of structural concept for deployable antenna was given out by aeronautic scholar . astromesh deployable antenna is one of them , which has most potential for space application 随着宇航科技的发展,各相关学科对空间可展天线提出了更高的要求,主要体现在大口径、高精度两方面,为此各国学者提出了形式众多的空间可展天线结构概念,环形桁架可展天线是其中最具潜力的结构形式之一,是本文研究的一个重要方面。
A large astromesh deployable antenna which is a project supported by state committee was designed and analyzed in this paper . the design and analysis process was described in detail . through the parallel analysis of four common type of cable - net for astromesh antenna and the parameterized analysis of every kind of structural parameter , the influence to static and dynamic characteristic of astromesh deployable antenna by the type of cable - net and every kind of structural parameter was given out 结合课题组承接的科研项目,对一大型环形桁架可展天线结构实例进行了设计与分析,对设计分析的各个环节进行了详细的阐述,通过对该类天线四种常用索网形式的对比分析及各类结构参数的参数化分析,得出了索网形式及各类结构参数对其静、动力特性的影响规律,对此类可展天线的设计具有指导意义。
