Abstract
We present unique static and dynamic behavior of cylindrical origami in triangular patterns. This cylindrical origami structure composed of triangular facets can support both axial and rotational motions under external excitations. To analyze the folding mechanism, we model each triangular facet as linear spring network to accommodate its deformations. We first examine the force-displacement relationship of a single unit cell. Our analysis results show transitions between monostable and bistable configurations by altering initial geometrical parameters. Based on this single cell analysis, we conduct dynamic analysis on a 1D chain of multiple unit cells stacked vertically in various arrangements to investigate its coupling of axial and rotational motions. This multi-cell analysis demonstrates the tunability of wave propagation in the 1D chain as well as frequency band structure formation. By leveraging their unique static/dynamic mechanisms, the origami-based mechanical structures have great potential for engineering applications, e.g., deployable aerospace structures.
