飞机库目标毁伤特性数值模拟分析

Numerical Study of Damage Modes and Damage Assessment of Hangars Under Attack

空军基地在战争中具有重要作用,机库常被视为火力打击的重点目标。因此,利用有限元程序,分别对软质和硬质PVC材质的五连机库在不同当量爆炸作用下的毁伤效果进行计算与分析,并与实际战例中遭受打击的机库真实毁伤效果进行对比,结果表明,在100 kg~500 kg TNT当量的爆炸作用下,直接命中的机库几乎完全被毁,相邻机库可部分毁伤;在相同的爆炸作用条件下,硬质PVC材质机库较软质PVC材质机库,棚顶的毁伤面积更大,但对库内设施具有更好的防护效果。

Air base plays an important role in the war,and hangar is often regarded as the key target of firepower attack.This paper uses LS-DYNA program to calculate and analyze the damage effect of soft and hard PVC hangars under different equivalent explosion,and compares with the real damage effect in actual combat cases.The results show that under the explosion of 100 kg-500 kg TNT equivalent,the hangar hit directly is almost completely destroyed,and the adjacent hangars can be partially destroyed;under the same explosion conditions,the damage area of hard PVC hangar is larger than that of soft PVC hangar,but it has better protective effect on the facilities in the hangar.
