Abstract

Current CubeSats usually exhibit a low structural mass efficiency and a low internal volume for their payloads. The present work aims to propose an advanced structural architecture for CubeSats that addresses the issues of low structural mass efficiency and payload volume. The starting concept is the smart tiles architecture for satellites developed for the ARAMIS (an Italian acronym for a highly modular architecture for satellite infrastructures) CubeSat project. By introducing multifunctional structures and lightweight, composite materials in the design of smart tiles, the volumetric and structural mass efficiency of the entire CubeSat are enhanced. The advantages of the chosen approach are preliminarily analyzed in terms of the volumetric efficiency and amplitude of the payload design space. A 1U battery tile design is then selected to investigate the multifunctional structures design aspects in the project of space structures. A battery tile prototype is designed, produced, and tested. The CubeSat volumetric increment and the payload volume gain with respect to the traditional architecture is shown to reach a maximum of 37%. The CubeSat structural mass ratio can be reduced to 16.7%.

用于立方体卫星的模块化多功能复合结构：嵌入式电池原型模态分析

目前的立方体卫星通常结构质量效率低，有效载荷内部体积小。目前的工作旨在为立方体卫星提出一种先进的结构架构，以解决结构质量效率低和有效载荷体积小的问题。起始概念是为 ARAMIS（意大利语，意为卫星基础设施高度模块化结构的缩写）立方体卫星项目开发的卫星智能瓦片结构。通过在智能瓦片设计中引入多功能结构和轻质复合材料，提高了整个立方体卫星的体积和结构质量效率。初步分析了所选方法在有效载荷设计空间的体积效率和振幅方面的优势。然后选择了一个 1U 电池瓦片设计来研究空间结构项目中的多功能结构设计方面。设计、生产和测试了电池瓦原型。与传统结构相比，立方体卫星的体积增量和有效载荷体积增量最大可达 37%。立方体卫星的结构质量比可降至 16.7%。
