小钨球侵彻单兵防护装备的弹道极限

Ballistic Limit of Low-Mass Tungsten Balls Penetrating Single Protective Equipment

选用0.16 g小质量钨球对防弹衣、防弹头盔和LY12CZ硬铝板进行侵彻实验,获得了相应的弹道极限,利用人体杀伤比动能标准计算得到了0.16 g小钨球对穿有防弹衣人员的有效杀伤速度。利用数值仿真方法计算得到了防弹衣和防弹头盔与LY12CZ硬铝靶的等效厚度,并计算了0.16 g、0.2 g、0.25 g、…、0.5 g的小质量钨球侵彻防弹衣和防弹头盔的弹道极限,分析了弹道极限随小钨球质量的变化规律,研究结果对单兵破片战斗部的设计具有指导作用。

0.16 g low-mass tungsten balls were selected for the penetration experiment on the bullet-proof vest,the bullet-proof helmet and LY12CZ hard aluminium target to obtain the corresponding ballistic limit and calculate the effective killing velocity of 0.16 g low-mass tungsten balls for those who are wearing bullet-proof vests according to the human body killing ratio kinetic energy standard.The equivalent thickness between the bullet-proof vest or the bullet-proof helmet and LY12CZ hard aluminium targets were obtained by numerical simulation method.The LY12CZ hard aluminium target was penetrated with 0.16 g,0.2 g,0.25 g,…,0.5 g low-mass tungsten balls respectively to obtain the ballistic limit and analyse the laws of the ballistic limit changing with the tungsten ball mass.The results of the study have a guiding role in the design of the single fragment warhead.
