Study on In-Plane Mechanical Behavior and Cushioning Property of Hexagonal Aluminum Honeycomb

为研究同一特征单元不同孔壁厚、不同冲击速度和不同压板重量对六边形铝蜂窝共面力学行为及缓冲性能的影响。采用数值模拟的方法,基于ANSYS仿真计算分析来研究孔壁厚为0.05mm、0.1mm、0.15mm六边形铝蜂窝材料分别在3种不同速度、8种载荷下共面冲击力学行为及其变形方式。得到不同参数下六边形铝蜂窝材料在不同冲击速度下的动态冲击行为中的力学特性曲线趋势和走向基本一致;得到不同孔壁厚下的三种变形方式。类比3种不同孔壁厚、同应力下其缓冲性能,得出C-σ_m曲线,为后期进一步研究铝蜂窝结构缓冲特性及其优化提供了理论基础。

To study on In-plane mechanical behavior and cushioning properties of hexagonal aluminum honeycomb with the same characteristic elements which have different pore wall thicknesses,different velocities and different platen weights.The method of numerical simulation was used to study the In-plane mechanics behavior and deformation of hexagonal honeycomb honeycombs with thicknesses of 0.05mm,0.1mm,and 0.15mm at 3 different speeds and 8 loads based on ANSYS simulation calculation and analysis.The trend and trend of the mechanical characteristic curves of the hexagonal aluminum honeycomb under different impact speeds under different impact speeds are basically consistent.There are 3 ways of deformation mode on different pore wall thicknesses.Comparing the cushioning properties of three different pore wall thicknesses under the same stress,get the C-σ_m curve.It provides a theoretical basis for the further study of the buffering characteristics and optimization of aluminum honeycomb structure.
