仿蜂窝防护结构的承载特性

In order to meet the requirements of structural safety, in this paper, first, the characteristics of high strength ratio and high mechanical properties of honeycomb structure were used for reference, and applies the principle of structural bionics to design and establish three simplified structure models, the direct honeycomb structure, oblique honeycomb structure and plate structure. Second, under five different working conditions, the finite element analysis software OptiStruct was used to analyze the bearing characteristics of three models. Finally, the three models were prepared by 3D printing technology, and the mechanical properties of the samples were tested and compared with that of simulation results. It is shown that the stress values at each position of the structure are similar to each other, and the structure has good mechanical conductivity. Under the condition of the same quality, the bearing capacity of the imitation oblique honeycomb structure is 12% higher than that of the imitation vertical honeycomb structure, and 150% higher than that of the plate structure. This work may provide a reference for the lightweight design of the protection structure.
