摘要
建立了正方形金属蜂窝铝芯13×8的蜂窝单元阵列有限元分析模型,研究了正方形金属蜂窝在共面压缩载荷作用下的变形形态,并分析了速度在3～250m/s时,正方形金属蜂窝铝芯的共面力学性能与其结构参数和速度之间的关系。当结构参数固定时,正方形金属蜂窝铝芯的峰应力与速度的平方成线性关系,而当速度固定时,峰应力与壁厚边长比成幂指数关系。
Finite element model of square metal aluminum honeycomb with 13 ×8 honeycomb cells was established. The deformation modes of square metal aluminum honeycomb under coplanar compression load were studied. The relationship of its coplane mechanical properties and structural parameters and velocity under 3-250m/s compression velocities was analyzed. The results showed that with fixed structural parameters, plateau stress of square metal aluminum honeycomb is proportional to the square of velocity; and with fixed velocity, plateau stress is the power law index of the ratio of thickness and edge length.
