摘要

为了得到具有良好压缩力学性能的填充材料，设计并制备出两种结构的正交梯形蜂窝铝(90°正交梯形蜂窝铝和45°正交梯形蜂窝铝),分析了准静态轴向加载下的材料的力学性能，并对两种结构的正交梯形蜂窝铝进行聚氨酯泡沫填充，分析聚氨酯填充对正交梯形蜂窝铝性能的影响。研究结果表明，相较于45°正交梯形蜂窝铝，90°正交梯形蜂窝铝的性能更优；两种结构的正交梯形蜂窝铝在聚氨酯填充后峰值应力、平台应力和单位体积吸收能得到明显的提升，但在吸能效率上填充聚氨酯后没有明显提升而且最大能量吸收效率对应的应变值减小。

Abstract

To obtain the filling material with good compression mechanical properties, two kinds of orthogonal trapezoidal honeycomb aluminum with different structures were manufactured（90°orthogonal trapezoidal honeycomb aluminum and 45° orthogonal trapezoidal honeycomb aluminum）, the mechanical properties of the material under quasi-static axial loading was analyzed. Two kinds of orthogonal trapezoidal honeycomb aluminum were filled with polyurethane foam, and the effect of polyurethane filling on the orthogonal trapezoidal honeycomb aluminum was analyzed. The results show that compared with 45° orthogonal trapezoidal aluminum honeycomb, the performance of 90° orthogonal trapezoidal honeycomb aluminum is better, and the peak stress, plateau stress and unit volume absorption energy of the two kinds of orthogonal trapezoidal honeycomb aluminum are improved after polyurethane filling. However, the energy absorption efficiency is not significantly improved after being filled with polyurethane, and the strain corresponding to the maximum energy absorption efficiency decreases.
