Infinitely-extensible single-degree-of-freedom wavy paper-cut structure and extension method thereof

Abstract

The invention relates to an infinitely-extensible single-degree-of-freedom wavy paper-cut structure and an extension method thereof. The structure comprises multiple isosceles triangle modules and multiple hexagonal modules, and the upper bottom edge and the lower bottom edge of any hexagonal module are parallel and are equal in distance; three edges of each isosceles triangle module are connecting edges, the upper bottom edge and the lower bottom edge of each hexagonal module are connecting edges, only one of the upper waist edge and the lower waist edge of each hexagonal module is a connecting edge, and the two edges are not adjacent; when the connecting edges are located on the non-edges of the paper-cut structure, only two adjacent modules need to be connected; the bottom connecting edge of the isosceles triangle module located on the non-edge is connected with the bottom connecting edge of another isosceles triangle module, and the two isosceles triangle modules are completely the same; the upper bottom connecting edge of the hexagonal module located on the non-edge is connected with the upper bottom connecting edge of another hexagonal module, the lower bottom connecting edge of the hexagonal module located on the non-edge is connected with the lower bottom connecting edge of another hexagonal module, and the two hexagonal modules are completely the same; and the right lower waist connecting edge of the hexagonal module located on the non-edge is connected with the left waist connecting edge of another isosceles triangle module, and the left lower waist connecting edge of the hexagonal module located on the non-edge is connected with the right waist connecting edge of another isosceles triangle module. The paper-cut structure has the extensible performance, and the folding and unfolding process is single degree of freedom.

Description

technical field [0001] The invention relates to an infinitely expandable kirigami structure, in particular to an infinitely expandable single-degree-of-freedom wavy kirigami structure and an expansion method thereof. Background technique [0002] In recent years, many engineers have applied origami to practical engineering applications, such as solar panels for spacecraft, foldable homes, and portable tents. The process is a single degree of freedom, which makes the change easier and more convenient. When not in use, it can be stored and transported with a small space occupation. Most origami structures are a complete two-dimensional plane, which is a board with no thickness by default. However, the influence of the thickness of the board needs to be considered in the application, making many origami structures unable to be applied in actual engineering. Nowadays, many researchers are also working on the problem of thick plate origami, and there is an urgent need for new t...
