A Curvature-Tunable Deployable Origami Boom with Facet-Integrated Self-Locking Mechanism

Abstract

Recent advances in technology have expanded the space industry, but there are still volume limitations 29 on carriers, which translates directly into cost. Deployable structures can overcome these limitations and 30 are used in especially in space in a variety of ways. In this paper, this study proposes a curvature-adjustable 31 origami boom incorporating a plane-induced -based self-locking mechanism. The Kirigami locker, which 32 deploys with the pattern and is self-locking, can increase rigidity while minimizing the increase in storage 33 volume. By utilizing the characteristics of the Miura pattern, the results show a difference in compressive 34 and bending stiffness of up to 6.29 and 3.5 times, respectively, with and without the locking segment. In 35 addition, the curvature can be freely designed through pattern variation, and booms with multiple 36 curvatures can be produced. This makes it possible to design a variety of highly rigid and deployable 37 structures, from small sizes such as tables to large structures such as shelters and masts, which can be 38 deployed with little DoF.
