聚焦破片战斗部破片质量对毁伤能力的影响分析

聚焦破片战斗部是防空导弹常用战斗部,由于战斗部总质量往往受限,因而分析在破片总质量不变的情况下单个破片质量对毁伤能力的影响十分必要。假定聚焦破片战斗部的破片总质量不变,为8kg],应用ANSYS/LS-DYNA有限元分析软件模拟不同质量破片打击靶弹不同目标舱段的毁伤效果,共进行了15种情况的数值模拟。模拟结果研究表明:单个破片质量为2 g]的战斗部对靶弹的整体杀伤效果最好。

Influence Analysis of Fragment Quality with Damage Ability About Fragment Focusing Warhead

Fragment focusing warhead is commonly used in anti aircraft missile. Since the total mass of the warhead is often limited, so the damage ability influenced by single fragment mass is necessary with unchanged total mass of the fragment. Assumed unchanged total mass of the fragment was 8 kg, it was simulated by using ANSYS / LS-DYNA finite element analysis software that fragments of different mass penetrated different target cabin. 15 cases of numerical simulation were carried. The simulation showed that damage ability of the warhead was best which mass of single fragment is 2g.
