Abstract

The spider orb web has evolved to efficiently absorb the energy of flying insects colliding with it. In this study, a novel three-dimensional lattice structure inspired by the specific structural characteristics of the spider orb web was designed and optimized to create a new lattice design. The design was optimized for energy absorption and energy absorption efficiency using a size optimization procedure with numerical modeling based on beam elements under quasi-static compression loading. This optimized lattice was additively manufactured and subjected to quasi-static compression testing. Numerical results for energy absorption and compression behavior showed good agreement with experimental findings. Additionally, numerical analysis of the optimized lattice was performed using solid elements to predict the energy absorption behavior more accurately, and the results showed even better agreement with experimental data. The resulting lattice also demonstrated improved energy absorption performance compared to existing lattice structures.

受蜘蛛网启发的能量吸收器

蜘蛛球网已经进化到可以有效地吸收与之相撞的昆虫的能量。在本研究中，受蜘蛛球网特定结构特征的启发，设计并优化了一种新的三维晶格结构。采用基于准静态压缩载荷的梁单元尺寸优化和数值模拟方法，对结构的能量吸收和能量吸收效率进行了优化设计。对优化后的晶格进行了增材制造和准静态压缩试验。能量吸收和压缩特性的数值计算结果与实验结果吻合较好。此外，利用固体元对优化后的晶格进行了数值分析，更准确地预测了能量吸收行为，结果与实验数据吻合得更好。与现有的晶格结构相比，所得到的晶格也显示出更好的能量吸收性能。

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
