摘要：

受螳螂虾虾螯微观Bouligand结构启发，本文以六边形、圆形、负泊松比、四边形4种胞元作为层间基础结构，建立了4种仿生螺旋结构以及4种对比结构。以热塑性聚氨酯材料为基材，运用3D打印技术进行结构制备。基于准静态压缩试验和数值模拟探究了上述8种结构的吸能性能。结果表明：4种仿生螺旋结构的吸能特性较好，其中仿生六边形螺旋结构比吸能可达531.65 mJ/g。与对应对比结构相比，4种仿生螺旋结构比吸能分别提升64.72%、32.39%、55.84%、25.14%，这表明层间螺旋堆叠分布有效增强了结构的吸能特性，结构变形破坏将会吸收更多的能量。

Abstract:

Inspired by the microscopic Bouligand structure of mantis shrimp， this paper used four cells （hexagonal， circular， quadrilateral and negative Poisson's ratio） as interlayer basic structures， and established four bionic helical structures and four contrast structures. Using the thermoplastic polyurethane material as the base material， the above structures were fabricated by 3D printing technology. Based on the quasi-static compression tests and numerical simulations， the energy absorption performance of the above eight structures was investigated. The results showed that the energy absorption characteristics of the four bionic helical structures were better， and the specific energy absorption of the bionic hexagon helical structure could reach 531.65 mJ/g. Compared with the corresponding contrast structure， the specific energy absorption of the four bionic helical structures increased by 64.72%， 32.39%， 55.84% and 25.14% respectively， which indicated that the helical stacking distribution between layers effectively increased the energy absorption characteristics of the structures. The deformation and failure of the structures would absorb more energy.
