| 中文摘要: |
| 建立了六边形蜂窝单元阵列的有限元模型，利用有限元分析软件分析研究了六边形金属蜂窝的异面冲击性能。当六边形蜂窝铝芯的各结构参数固定时，在不同的冲击速度下，研究了壁厚边长比对其异面冲击动态峰应力的影响规律。根据有限元模拟计算结果，给出了所用六边形蜂窝铝芯样品异面动态峰应力的计算公式。 |
| 英文摘要: |
| Finite element model of hexagonal honeycombs cell arrays was established. The out-of-plane impact performance of hexagonal metal honeycombs was studied by using finite element method. When all configuration parameters of hexagonal metal honeycombs were kept constant, under different impact velocities, dynamic compression test was simulated to study the influences of wall thickness on out-of-plane impact performance of hexagonal honeycombs. The formula to calculate the out-of-plane plateau stresses of hexagonal aluminum honeycombs was been given based on the finite element analysis results. |
