摘要
利用有限元仿真软件ABAQUS/Explicit,研究了铝蜂窝板结构的冲击动力学特性,分析了冲击速度对铝蜂窝材料等效塑性应变和能量吸收特性的影响。结果表明,随着冲击速度的增大,上表面铝板和铝蜂窝芯的最大等效塑性应变也随之增大,同时,铝蜂窝板的吸收能量也随之变大,但是铝蜂窝板的总体能量吸收率变小。
The impact dynamics of aluminum honeycomb panel structure is studied by finite element simulation software ABAQUS/Explicit. The effects of equivalent plastic strain and energy absorption characteristics of aluminum honeycomb materials are investigated by different impact velocities. In the numerical simulation, it is found that as the impact velocity increases, the maximum equivalent plastic strain of the upper aluminum plate and the aluminum honeycomb core also increases, and the absorption energy of the aluminum honeycomb plate also increases, but the overall energy absorption rate of aluminum honeycomb plate is getting smaller.
