Adaptable CubeSat Structure for Additive Manufacturing · 模型 258457
Our 3D printed CubeSat structure takes advantage of recent developments in additive manufacturing to provide a simplified design, ideal for customisation to suit a range of CubeSat payloads and purposes. We believe it is inevitable that plastic structures produced by fused deposition will eventually find their way into orbit, due to their ease of accessibility for students, hobbyists, and start-ups alike, and thus we embarked on this project as a study of potential design ideas and capabilities. We have prototyped a variant of this design, which required modification due to the capabilities of 3D printing facilities available to us, and a range of validation tests are ongoing. Our structure is designed for production from high tensile-strength plastics (such as PEEK), though initial prototypes have been created from VeroWhite due to its availability at the Sydney Invention Studio. Depending on the results of future testing, where significant challenges still remain in the analysis of material strength, out-gassing, and resistance to the orbital radiation environment, a pivot towards metal-based production may be pursued, in which case the design could be further cut-down to eliminate unnecessary material. A more comprehensive analysis of the structure we have designed for The Cubesat Challenge is available in an attached document. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Design Features and Advantages Our structural design includes a range of advantageous properties, which allow it to build upon and extend existing CubeSat technologies: - Additive manufacturing with plastics is both fast and inexpensive, allowing rapid prototyping and design iteration, particularly important for student teams and startups where agile development and major design pivots are common. - PEEK and Nylon provide substantially reduced density in comparison to traditional metal-based structures, whilst only requiring minor thickening to make up for their inferior strength properties, meaning overall mass can be reduced substantially. - Our design can accommodate standard PC104 system boards, allowing existing technologies to be integrated, thus reducing CubeSat project development and production costs. - Additive manufacturing allows varying material thicknesses to combat localised stress concentrations, which in our design means stronger support for vertical rails, and tapered thicknesses on end faces to provide superior strength ne...
