Geometric assembly of rigid-foldable morphing sandwich structures

摘要: Morphing plate-based sandwich mechanisms consist of three layers: an inner core designed to achieve a particular deployed geometric envelope and two outer faces preserve rigid-foldability from flat-folded form. This paper examines rigid-foldable morphing based on the Miura rigid origami pattern. An alternative mechanism is developed that has improved stability locking capability compared with existing reported previously. These improvements are demonstrated steel prototypes. The then extended form family new structures, including fan-shaped mechanism, single-curved cylindrical conical mechanisms. Each derived by substituting base pattern Miura-derivative pattern, attaching have compatible avoid self-intersection during deployment. derivations validated physical
