摘　　要：为提高多爆炸成型弹丸(MEFP)对装甲目标的毁伤效能,提出了一种新型组合式端面MEFP聚能装药结构,该结构能成型一枚“杆式”的中心弹丸和12枚“拳状”的周向辅助弹丸,可对装甲目标产生多点毁伤效应。研究基于该方案的可行性,进一步研究了装药长径比,辅罩厚度、高度、径向跨度对其成型特性、侵彻性能的影响规律。研究发现:当装药长径比增大时,辅助弹丸速度逐渐增大,飞散角则先增大后减小;当辅罩厚度和高度增大时,其速度逐渐减小,飞散角则逐渐增大;当辅罩径向跨度增大时,其速度逐渐增大,飞散角逐渐减小。研究设计的MEFP可有效穿透12 mm厚45#钢靶,能够实现对装甲面目标的毁伤半径可控(调节飞散角),研究结论可为末敏弹战斗部威力设计提供参考依据。In order to improve the damage efficiency of a multi explosive forming projectile(MEFP)to armored targets,this paper proposes the shaped charge structure of a new type of modular end face MEFP.This structure can form a“rod”central projectile and 12“fist-shaped”circumferential auxiliary projectiles,which can produce multi-point damage effect to armored targets.Based on the feasibility of this scheme,the effects of charge length diameter ratio,auxiliary liner thickness,auxiliary liner height and radial span on its forming characteristics and penetration performance are further studied.It is found that when the length diameter ratio of charge increases,the velocity of auxiliary projectiles gradually increases,and the scattering angle first increases and then decreases.When the thickness and height of the auxiliary liner increase,its velocity decreases gradually,and the scattering angle increases gradually.When the radial span of the auxiliary liner increases,its velocity gradually increases and the scattering angle gradually decreases.The designed MEFP warhead can effectively penetrate the 45#steel target of a thickness of 12 mm,and can realize the controllable damage radius of the armored surface targets(the adjusted scattering angle).The research conclusion can provide a reference for the power design of terminal sensitive warheads.
