模块化可展开天线地面展开测试系统、控制方法及应用Modular deployable antenna ground deployment test system, control method and application

技术领域technical field

本发明属于卫星天线技术领域,尤其涉及一种模块化可展开天线地面展开测试系统、控制方法及应用。The invention belongs to the technical field of satellite antennas, and in particular relates to a ground deployment test system, control method and application of a modular deployable antenna.

背景技术Background technique

目前,星载可展开天线是卫星结构的重要组成部分,随着航天科技、卫星通讯、深空探测等航天事业的发展,对星载可展开天线提出了越来越多地要求,主要包括对口径大、质量轻、体积小以及展开过程平稳等方面的要求。模块化空间可展开天线作为一种“模块拼接”的可收展的天线无疑在未来的卫星天线的发展中将发挥着重要的作用,如何进行合理有效的地面实验研究是研究可展开天线的重要环节。At present, the spaceborne deployable antenna is an important part of the satellite structure. With the development of aerospace technology, satellite communication, deep space exploration and other aerospace industries, more and more requirements have been put forward for the spaceborne deployable antenna, mainly including Large caliber, light weight, small volume and stable deployment process. The modular space deployable antenna, as a "module splicing" retractable antenna, will undoubtedly play an important role in the development of satellite antennas in the future. How to conduct reasonable and effective ground experimental research is an important factor in the study of deployable antennas. link.

由于采用压簧作为驱动力源的模块化可展开天线不同于周边桁架等柔索提供驱动力的可展开天线,弹簧具有在受压状态下始终保持有伸展的趋势并将所存储的弹形势能转化为机构展开运动的动能,以及展开过程中天线背架始终处于变化的空间曲面之上基于以上等特点,目前对于模块化可展开天线的地面展开控制方案主要是通过建立悬挂桁架,将天线吊装以完成地面展开试验。该地面展开控制方案主要通过在天线模块上添加绕线轮机构来控制天线的平稳展开,并在展开控制装置中添加旋转支撑机构以保证适应天线在展开过程中不断变化的背架曲面。哈尔滨工业大学(田大可.模块化空间可展开天线支撑桁架设计与实验研究[D].哈尔滨工业大学,2011)建立天线悬挂桁架实进行地面展开试验。由于控制索由卷筒释放出后直接连接到下一层模块,由于卷筒采用分层布置,连接每一模块的控制索分别位于不同层间,由于卷筒上每一层对应的高度不同,无法保证控制索释放端与其对应模块的空间距离都相同,同时存在对于大型模块且模块拼装在一起的情况下,悬吊装置都难以建立,受限于场地空间的限制,同时天线的高度过大,难以进行安装等多方面问题。Since the modular deployable antenna that uses the compression spring as the driving force source is different from the deployable antenna that provides the driving force with flexible cables such as peripheral trusses, the spring has the tendency to always expand under the state of compression and store the elastic energy. It is converted into the kinetic energy of the unfolding motion of the mechanism, and the antenna back frame is always on the changing space surface during the unfolding process. Based on the above characteristics, the current ground deployment control scheme for the modular deployable antenna is mainly to build a suspension truss to hoist the antenna. to complete the ground deployment test. The ground deployment control scheme mainly controls the smooth deployment of the antenna by adding a winding wheel mechanism on the antenna module, and adds a rotating support mechanism to the deployment control device to ensure that it can adapt to the changing back frame surface of the antenna during deployment. Harbin Institute of Technology (Tian Dake. Design and experimental research of modular space deployable antenna support truss [D]. Harbin Institute of Technology, 2011) to establish an antenna suspension truss and conduct ground deployment tests. Since the control cable is directly connected to the next layer of modules after being released from the reel, and since the reel is arranged in layers, the control cables connecting each module are located between different layers. There is no guarantee that the space distance between the release end of the control cable and its corresponding module is the same. At the same time, in the case of large modules and the modules are assembled together, it is difficult to establish a suspension device, which is limited by the limitation of site space, and the height of the antenna is too large. , difficult to install and many other problems.

通过上述分析,现有技术存在的问题及缺陷为:现有技术中由于卷筒采用分层布置,连接每一模块的控制索分别位于不同层间,由于卷筒上每一层对应的高度不同,无法保证控制索释放端与其对应模块的空间距离都相同,同时存在对于大型模块且模块拼装在一起的情况下,悬吊装置都难以建立,受限于场地空间的限制,同时天线的高度过大,难以进行安装等多方面问题。Through the above analysis, the existing problems and defects in the prior art are: in the prior art, since the drums are arranged in layers, the control cables connecting each module are located between different layers, and the heights corresponding to each layer on the drum are different. , there is no guarantee that the space distance between the release end of the control cable and its corresponding module is the same. At the same time, for large modules and the modules are assembled together, it is difficult to establish the suspension device, which is limited by the limitation of site space, and the height of the antenna is too high. Large, difficult to install and many other problems.

解决以上问题及缺陷的难度为:难以保证控制索释放量的均匀性从而难以保证展开过程的平稳性,因为控制索如果在绕线装置上简单的缠绕不施加导向以及在缠绕位置不加限制,难以保证每一根控制索的角度以及释放量,使得天线展开不均匀以及控制索索力不均匀。同时在展开过程中各个模块的背架处于一个变化的空间曲面之上,要想摆脱对于悬挂桁架进行展开实验,难以为天线施加有效的支撑,因为支撑点的高度时刻都在变化。The difficulty of solving the above problems and defects is: it is difficult to ensure the uniformity of the release amount of the control cable and thus the stability of the unwinding process, because if the control cable is simply wound on the winding device without applying guidance and no restrictions on the winding position, It is difficult to ensure the angle and release amount of each control cable, resulting in uneven deployment of the antenna and uneven force of the control cable. At the same time, during the deployment process, the back frame of each module is on a changing space surface. In order to get rid of the deployment experiment of the suspension truss, it is difficult to provide effective support for the antenna, because the height of the supporting point changes all the time.

解决以上问题及缺陷的意义为:保证了天线展开的平稳性,这是展开天线结构的关键问题之一,同时设计转动以及滑动于一体的支撑,保证了支撑可以适应天线展开的曲面的变化,为地面展开实验带来了极大的便利。The significance of solving the above problems and defects is: to ensure the stability of the antenna deployment, which is one of the key issues in the deployment of the antenna structure, and to design a support that integrates rotation and sliding to ensure that the support can adapt to the changes in the curved surface of the antenna deployment. It brings great convenience to the ground experiment.
