摘要

将卫星发射到地球轨道是一个关键的研究领域,随着现代社会的形成,对卫星服务的要求越来越高。与此同时,由于开发和发射卫星任务的成本较高,开发时间较短,因此需要在多个工程领域采用新的方法来建造、测试、发射和运行地球轨道以及其他天体轨道上的卫星。有可能节省发射成本的一个领域是卫星的结构完整性,特别是在发射阶段,火箭运动产生的最大振动和随后的应力可能会影响卫星的生存能力。为了解决这个问题,两个重要的工程领域联合起来提供了新颖、完整和有竞争力的解决方案:拓扑优化方法和快速成型制造。一方面,拓扑优化方法是一种数学方法,可以通过单目标或多目标函数的最大化或最小化以及多种类型的算法,迭代优化结构(通常是通过降低质量),同时根据应用情况(例如承载能力)改善某些结构特性。过去 30 年来,该领域一直非常活跃,主要有两大类核心算法:修改密度等连续参数的连续法和在网格中添加和删除材料元素的离散法。另一方面,增材制造技术是最近出现的制造工艺,旨在彻底改变制造和供应链。增材制造技术的主要代表是选择性激光熔融技术(SLM)(3D 打印)和电子束熔融技术(EBM)。最近的趋势表明,通过增材制造工艺使用新型材料建造拓扑优化结构,可以提供更便宜的先进结构,这些结构经过全面优化,在外层空间环境中性能更佳,尤其是作为新型卫星系统结构子系统的一部分。这项工作旨在对结构拓扑优化的主要方法以及航空航天领域的增材制造进行扩展回顾,尤其侧重于卫星结构,这可能为未来五到十年卫星结构的发展奠定基础。

On Topology Optimisation Methods and Additive Manufacture for Satellite Structures: A Review
Launching satellites into the Earth’s orbit is a critical area of research, and very demanding satellite services increase exponentially as modern society takes shape. At the same time, the costs of developing and launching satellite missions with shorter development times increase the requirements of novel approaches in the several engineering areas required to build, test, launch, and operate satellites in the Earth’s orbit, as well as in orbits around other celestial bodies. One area with the potential to save launching costs is that of the structural integrity of satellites, particularly in the launching phase where the largest vibrations due to the rocket motion and subsequent stresses could impact the survival ability of the satellite. To address this problem, two important areas of engineering join together to provide novel, complete, and competitive solutions: topology optimisation methods and additive manufacturing. On one side, topology optimisation methods are mathematical methods that allow iteratively optimising structures (usually by decreasing mass) while improving some structural properties depending on the application (load capacity, for instance), through the maximisation or minimisation of a uni- or multi-objective function and multiple types of algorithms. This area has been widely active in general for the last 30 years and has two main core types of algorithms: continuum methods that modify continuous parameters such as density, and discrete methods that work by adding and deleting material elements in a meshing context. On the other side, additive manufacturing techniques are more recent manufacturing processes aimed at revolutionising manufacturing and supply chains. The main exponents of additive manufacturing are Selective Laser Melting (SLM) (3D printing) as well as Electron Beam Melting (EBM). Recent trends show that topology-optimised structures built with novel materials through additive manufacturing processes may provide cheaper state-of-the-art structures that are fully optimised to better perform in the outer-space environment, particularly as part of the structure subsystem of novel satellite systems. This work aims to present an extended review of the main methods of structural topology optimisation as well as additive manufacture in the aerospace field, with a particular focus on satellite structures, which may set the arena for the development of future satellite structures in the next five to ten years.
