The invention belongs to the technical field of flexible skin structures, and particularly relates to an olive-like zero-Poisson-ratio honeycomb unit cell structure and a flexible skin sandwich. Each olive-like zero-Poisson-ratio honeycomb unit cell structure comprises four inclined cell walls and two horizontal cell walls, the two vertically symmetrical inclined cell walls jointly form an olive-like honeycomb unit, the two olive-like honeycomb units are bilaterally symmetrical, one ends of the two symmetrical olive-like honeycomb units are connected tightly, and the other ends of the two symmetrical olive-like honeycomb units are open and not connected. The two horizontal cell walls are respectively positioned on the upper side and the lower side of the olive-like honeycomb unit; and the flexible skin sandwich is formed by arranging a plurality of olive-like zero-Poisson-ratio honeycomb unit cell structures in an array. The olive-like zero-Poisson-ratio honeycomb unit cell structure has good out-of-plane bearing capacity of a sinusoidal honeycomb unit cell structure, and also has in-plane stretching and compression large deformation performance.
本发明属于柔性蒙皮结构技术领域,具体涉及一种类橄榄状的零泊松比蜂窝单胞结构及柔性蒙皮夹芯。类橄榄状的零泊松比蜂窝单胞结构包括四个倾斜胞壁和两个水平胞壁,所述两个上下对称的倾斜胞壁共同构成了类橄榄状蜂窝单元,两个类橄榄状蜂窝单元左右对称且两个对称的类橄榄状蜂窝单元一端连接紧闭另一端开口不连接,两个水平胞壁分别位于所述类橄榄状蜂窝单元的上下两侧;柔性蒙皮夹芯由多个所述类橄榄状的零泊松比蜂窝单胞结构阵列排布构成。该类橄榄状的零泊松比蜂窝单胞结构具备正弦形蜂窝单胞结构良好的面外承载能力的同时,又可兼顾面内的拉伸和压缩大变形性能。
