Infinitely expandable single-degree-of-freedom wavy kirigami structure and its expansion method

Abstract

The invention relates to an infinitely expandable single-degree-of-freedom wavy kirigami structure and an expansion method thereof, including various isosceles triangular modules and various hexagonal modules, and the upper and lower bases of any hexagonal module are parallel and the distances are equal; the three sides of the isosceles triangle module are connecting sides, the upper and lower bases of the hexagonal module are connecting sides, and only one of the upper and lower waist sides of the hexagonal module is a connecting side, and the two The strip sides are not adjacent; when the connection side is at the non-edge of the kirigami structure, it must be connected and only two adjacent modules are connected; the bottom connection side of the non-edge isosceles triangle module is connected to the bottom connection side of another isosceles triangle module , and the two isosceles triangle modules are exactly the same; the upper bottom connecting edge of the non-edge hexagonal module is connected to the upper bottom connecting edge of the other hexagonal module, and the lower bottom of the non-edge hexagonal module The connecting edge is connected to the lower connecting edge of another hexagonal module, and the two hexagonal modules are identical. The kirigami structure has expandability, and the folding process is a 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...
