针对末敏弹对有生目标杀伤能力弱的问题,基于EFP战斗部结构,提出了一种轴向EFP药型罩结构并且周向装填预制破片的战斗部结构布局.利用仿真软件对EFP的成型与预制破片的飞散进行了数值模拟.仿真结果表明,周向装填预制破片对EFP的成型没有影响,而且预制破片的速度与分布较好.因此,周向装填预制破片可以增强末敏弹对软目标杀伤能力. In view of the weak killing ability of the end-sensitive projectiles against living targets, an axial EFP drug-type cover structure is proposed based on the structure of the EFP warhead, and the warhead structure layout of the prefabricated fragments in the circumferential direction is proposed. And the scattering of prefabricated fragments were simulated.The simulation results show that the circumferential prefabricated fragments have no effect on the forming of EFP, and the prefabricated fragment velocity and distribution are better.Therefore, Target lethality.
