摘要

摘要: 基于非线性有限元软件LS-DYNA,通过在TNT炸药底部布置预制破片模拟战斗部爆炸产生的冲击波与破片联合作用载荷,计算3种TNT炸药当量下I型夹层板的毁伤响应,分析冲击波单独作用及冲击波与破片联合作用下I型夹层板失效模式的差异,研究夹层板芯层配置以及上、下面板厚度配置对其失效模式的影响,并与等效实体板的抗毁伤性能进行对比。同时,从吸能的角度分析不同载荷工况下I型夹层板的吸能特性。数值仿真结果表明:在冲击波与破片联合作用下,结构的毁伤程度远大于冲击波单独作用时;当载荷强度较小时,I型夹层板的抗毁伤性能优于等效实体板;载荷强度、载荷类型(冲击波单独作用或冲击波与破片联合作用)及上、下面板厚度配置对I型夹层板的失效模式有较大影响;从吸能特性来看,在冲击波单独作用下,上面板和芯层是主要的吸能构件,而在冲击波与破片联合作用下,上面板和下面板是主要的吸能构件。

Abstract: In this paper, the combined blast and fragment loads due to close-in warhead explosion is simu-lated by placing prefabricated fragments at the bottom of bare TNT explosive, and the corresponding dam-age on I-core sandwich panels are evaluated using the software LS-DYNA. The differences of failure modes of sandwich panels subjected to only blast and combined blast and fragment loads are analyzed, and the effects of core configuration and thickness configuration between the front and back plates on the fail-ure modes are studied. The anti-damage performance of sandwich panels is then compared with that of the equivalent solid plate. In addition, the energy absorption characteristics of I-core sandwich panels under different loads are also analyzed. Numerical results show that the overall damage of both the sandwich pan-els and solid plates subjected to combined blast and fragment loads is more severe than that caused by blast only. The performance of I-core sandwich panels is superior to equivalent solid plates when the load-ing intensity is small. It is also found out that the loading intensity, loading type (blast loading or combined blast and fragment loading) and the thickness configuration between the front and back plates yield signifi-cant influences on the failure modes of the I-core sandwich panel. From the results of energy analysis, it can be concluded that the front face plate and the core are the main energy-absorbing parts under blast loading, while the front and back face plates become the main energy-absorbing parts when combined blast and fragment loading is considered.
