New Publication: Rigid Folding of Generalized Waterbomb Origami Tubes
From: Date: 2021-01-06 Origami is capable of transforming a 2D crease pattern into a complex 3D sculpture. It has been widely used in engineering fields due to its capability of being lightweight, safe, customizable and easy to fabricate. Since the mechanical properties of origami structures are dominated by their folding deformation mode, the accurate theoretical description of the folding motion of origami structures is the foundation for their design and precise control in engineering applications. However, the folding behavior of most general origami structures is very difficult to analyze because of the lack of theoretical model and analysis methodology for the complex mobile assemblies of spherical linkages.
Geometrical parameters and folding sequences of generalized Waterbomb origami tubes
The effect of various geometrical parameters on the rigid contract and twist motion behavior, bifurcation property as well as physical blockages of the generalized Waterbomb origami tube were studied. The transition between rigid folding and structural deformation was also revealed.
