Geometric gradient plate structure

Abstract

The invention discloses a geometric gradient plate structure. The geometric gradient plate structure is formed by splicing at least two modules in two mutually orthogonal directions. The two mutuallyorthogonal directions are the horizontal direction and the vertical direction correspondingly, and the gradient plate structure can infinitely extend to be overlaid in the vertical direction and the horizontal direction. Each module is folded according to a miura folded paper pattern, each miura folded paper pattern is a mirror symmetry figure formed by splicing four completely-identical parallelograms and has one degree of freedom, and complete folding and unfolding can be achieved. According to the geometric gradient plate structure of changing the parameters of the modules in a column or line manner to achieve the space folding and unfolding characteristics, the parameters of the modules comprise the side length, in the horizontal direction, of the modules, the side length, in the vertical direction, of the modules, the included angle and the number of the modules. By means of the structure, free folding of a certain degree can be achieved, the structure can be self-locked when reaching a limiting point, the bearing capacity of the structure can be rapidly improved, and the self-locking point can be set through adjustment of geometric parameters.

Description

technical field [0001] The invention relates to a folded structure with geometric gradient properties, in particular to a geometric gradient plate structure with pre-folding and geometric gradient properties. Background technique [0002] Miura origami was proposed from the very beginning. Due to its space-folding characteristics, it has been applied to the aerospace field and subsequently applied to many daily life productions. For example, the patent name is "panel that can be quickly folded and unfolded", and the patent publication number is CN105757438A. With the deepening of research, Miura origami is gradually applied to the sandwich structure as the folded core layer. Compared with the traditional honeycomb structure, this structure has unique advantages: (1) The preparation process of the folded core layer is easy to realize, maintains the continuous integrity of raw materials, and can realize large-scale and automatic production; (2) The inside of the folded core la...

But at the same time, the traditional Miura structure is composed of repeated superposition of identical units, and the overall structure remains uniform, which cannot better adapt to complex external loads.
