Abstract
Deployable and origami-based structures are increasingly used in space exploration for their space efficiency and adaptability, but their complexity introduces reliability concerns. This paper presents a novel deployment method using elastodynamic energy localization and Flexible Frangible Links (FFLs). A wireless, synchronized IMU system measured antenna dynamics, while a hybrid Particle Swarm–Grey Wolf Optimization model identified optimal FFL placement. A frequency sweep analysis revealed natural frequencies that localized energy at specific joints, enabling selective unlatching. To validate this under realistic conditions, a gravity-offset air-table testbed with lightweight Z-fold antenna analogs was developed, demonstrating consistent and predictable tip release at targeted frequencies. Together, optimization, frequency selection, and gravity-offset testing establish a framework for reliable, frequency-driven deployment of origami-inspired space structures, advancing the efficiency and robustness of adaptive spacecraft systems.
