Description

一种板架式小卫星保型工装A plate frame type small satellite shape-preserving tooling

技术领域technical field

本发明涉及一种板架式小卫星保型工装,属于卫星总装设计领域,特别适用于批量生产的板架式低轨互联网卫星使用。The invention relates to a plate-frame type small satellite shape-preserving tool, belonging to the field of satellite assembly design, and is particularly suitable for the use of plate-frame low-orbit Internet satellites produced in batches.

背景技术Background technique

近年来,全球低轨互联网星座领域发展迈入高峰期,以Iridium-Next、OneWeb、Starlink等星座为引领、“群雄逐鹿”抢占市场先发位置的态势凸显,行业已经迈入竞争淘汰的实质性阶段。为提升批产效率,低轨互联网卫星普遍采用模块化设计,基于单板或模块并行总装,卫星根据发射重量不同采用板架式或框架式承力结构。例如,以OneWeb为代表的小卫星(发射重量200kg)采用了板架式结构而非Iridium-Next卫星(发射重量860kg)的框架式结构,以提升结构使用效率。与框架式结构可以提供可靠稳定的装配基准不同,板架式卫星在结构分解、模块总装、对接集成等多种工况下,依靠结构板孔位精度及自身刚度,难以满足卫星总装所需的结构变形和形位精度要求,对卫星总装质量造成了不良影响,严重制约了卫星批产的效率。In recent years, the development of the global low-orbit Internet constellation field has entered a peak period. Led by Iridium-Next, OneWeb, Starlink and other constellations, the trend of "competing for the best" to seize the market's first-mover position has become prominent, and the industry has entered a substantial phase of competition and elimination. stage. In order to improve the efficiency of mass production, low-orbit Internet satellites generally adopt a modular design, based on the parallel assembly of single boards or modules, and the satellites adopt a plate-type or frame-type load-bearing structure according to different launch weights. For example, the small satellite represented by OneWeb (launch weight 200kg) adopts a plate-frame structure instead of the frame structure of the Iridium-Next satellite (launch weight 860kg) to improve the efficiency of structure use. Different from the frame-type structure, which can provide a reliable and stable assembly reference, the plate-type satellite is difficult to meet the requirements of the satellite assembly under various working conditions such as structural decomposition, module assembly, and docking integration, depending on the hole position accuracy of the structural plate and its own rigidity. Structural deformation and shape and position accuracy requirements have adversely affected the quality of the satellite assembly and severely restricted the efficiency of satellite mass production.

如图8所示,为提升卫星批产效率,卫星采用模块化设计并行总装。首先,将卫星结构分解为载荷模块(包括+Z结构板和+X结构板)及平台模块(包括-Z结构板和-X结构板);之后,按模块并行开展总装、集成与测试工作;完成后,将载荷模块与平台模块重新对接集成为卫星整体。在卫星载荷模块与平台模块结构分解、模块总装、对接集成工况下,需要重点解决结构板变形和相对位置精度保持问题,保型工装使用步骤如下(模块对接过程按逆序进行):As shown in Figure 8, in order to improve the efficiency of satellite batch production, the satellite adopts a modular design and is assembled in parallel. First, the satellite structure is decomposed into load modules (including +Z structural plates and +X structural plates) and platform modules (including -Z structural plates and -X structural plates); after that, the general assembly, integration and testing work are carried out in parallel according to the modules; After completion, the payload module and the platform module are re-docked and integrated into the satellite as a whole. Under the conditions of structural decomposition, module assembly, and docking integration between the satellite load module and the platform module, it is necessary to focus on solving the problems of structural plate deformation and relative position accuracy maintenance. The steps for using the shape-preserving tooling are as follows (the module docking process is performed in reverse order):

首先,将+Z板保型框1与载荷模块+Z结构板连接,主体框架101、端部加强梁102和中部加强梁104共同构成“日”字型封闭式传力结构,减小+Z结构板安装大重量载荷设备下的结构变形。采取上述措施后,可实现卫星起吊、停放等工况下天线安装区域结构相对变形量≤0.2mm,满足天线安装变形要求;First, connect the +Z plate shape-preserving frame 1 to the load module +Z structural plate, the main frame 101, the end reinforcement beams 102 and the middle reinforcement beams 104 together form a "Sun"-shaped closed force transmission structure, reducing the +Z Structural deformation under the installation of heavy load equipment on structural panels. After the above measures are taken, the relative deformation of the antenna installation area under the working conditions of satellite lifting and parking can be realized ≤ 0.2mm, which meets the requirements of antenna installation deformation;
