Form-Finding and Optimization of Tensegrity Structures for Space Applications: A Study on Load-Bearing Capability and Packaging Efficiency of Tensegrity Space Masts

Abstract

This thesis investigates the optimization of tensegrity structures for use in space applications, focusing on factors such as packaging efficiency, structural stability, and load-bearing capacity. Tensegrity structures, composed of an interconnected network of struts and cables, offer unique advantages for space applications, such as their lightweight and deployable nature. We explore various symmetric prismatic tensegrity models with different numbers of struts per stage and stages per tower to explore the optimal configuration for meeting the demands of space applications. We manufacture tensegrity structures using 3D-printed struts and copper wires, with assembly carried out in a two-dimensional fashion before transforming them into three-dimensional structures. The manufacturing process and materials are discussed, along with potential sources of error and opportunities for improvement. Measurements, including height, radius, overlap, and weight, are gathered for each model, and their load-bearing capabilities are tested using an Instron Machine 5969. The results reveal trends related to the number of struts and stages in the towers, providing insights into the optimal configuration for achieving the desired structural properties. This thesis contributes to the understanding of tensegrity structures and their potential for space applications, paving the way for further research and development of these innovative structures for use in space exploration and beyond.
