Elastodynamic Structural Deployment with Frangible Unfolding

Deployable and origami-based structures are increasingly used in space exploration for their space efficiency, launchability, 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 inertial measurement unit 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.
