Variable cross-section gradient hierarchical honeycomb-like structure
The invention provides a variable cross-section gradient hierarchical honeycomb-like structure, which comprises a plurality of groups of cell structures, each cell structure comprises a circular cell element, a plurality of stages of square cell elements are arranged in each circular cell element, each square cell element extends outwards along the direction of four vertexes to form four cell element ribs, and each cell element rib is provided with a plurality of through holes. The other ends of the cell element ribs are connected with the circular cell elements on the outermost layer, and the gradient hierarchical honeycomb-like structure is composed of the circular cell elements and multi-stage square cell elements; the gradient hierarchical honeycomb-like structure is bent and stretched by a certain radian in the vertical direction to form a three-dimensional variable cross-section structure with a certain wall thickness, and then the gradient hierarchical honeycomb-like inner core structure is formed. The problems that a traditional honeycomb structure is insufficient in mechanical property, limited in application range and the like are solved.
本发明提供了一种变截面梯度层级类蜂窝结构，包括多组胞元结构，所述胞元结构包括圆形胞元件，在圆形胞元件内设有多级正方形胞元件，所述正方形胞元件沿着四个顶点方向分别向外延伸出四条胞元筋，所述胞元筋的另一端分别与最外层的圆形胞元件相连，所述梯度层级类蜂窝结构由圆形胞元件和多级正方形胞元件所构成；通过将梯度层级类蜂窝结构向竖直方向弯曲拉伸一定弧度形成带有一定壁厚的三维立体变截面结构，进而形成梯度层级类蜂窝内芯结构。用于改善传统蜂窝结构力学性能不足，应用范围有限等问题。
