摘要

随着作战环境日益复杂、时敏目标不断涌现，现代战场对战斗部多用途综合毁伤能力提出了更高的要求。针对战斗部多目标打击需求，基于爆炸成型弹丸（Explosively Formed Penetrator，EFP）/预制破片复合战斗部开展轴向聚能/杀伤复合毁伤元成型特性研究，得到不同战斗部结构参数对EFP成型特性及预制破片飞散特性的影响规律，并通过战斗部静爆试验进行验证。研究结果表明：药型罩结构参数（锥角

、罩厚

）主要影响EFP成型和预制破片飞散角，对预制破片速度的影响较小，其变化幅值不超过50 m/s；挡环角度

、壳体厚度

主要影响预制破片的散布特性，速度幅值超过200 m/s，飞散角变化幅度最高达到200%，但其对EFP成型的影响显著降低；起爆点数

主要影响EFP成型，其弹丸头部速度增益超过300 m/s，长径比增幅约为30%，但对预制破片的速度无增益效果，仅影响其飞散角；轴向EFP/预制破片复合毁伤元的成型过程中EFP的成型独立性较强，主要取决于药型罩结构与起爆方式；预制破片的飞散特性则因径向运动时内外层钨球碰撞产生的能量交换，涉及较多影响因素，需要开展多结构参数的耦合设计。通过战斗部静爆试验验证，复合战斗部可形成轴线方向初速1950m/s的高速弹丸和飞散速度700~830m/s、散布范围0.543°~7.48°钨球列阵，预制破片能够穿透5m距离处的8mm钢板。相关结论可为轴向多毁伤元/复合效应战斗部结构优化设计和毁伤效能提升提供参考。

Abstract

With the growing complexity of combat environments and the constantemergence of new time-sensitive targets

modern battlefields demand enhanced multi-purpose and comprehensive damage capabilities from warheads.The formation characteristics of axial shaped-charge/fragmentation composite damage elementswereinvestigatedusing an EFP(Explosively Formed Penetrator)/preformed fragment composite warhead to addr

ess multi-target engagement requirements. The effects of various warhead structural parameters on EFP formation and fragment dispersion were analyzed and validated through static detonation tests. Results indicate that liner parameters (cone angle

thickness

) primarily influence EFP formation and fragment dispersion angle

with limited effect on fragment velocity (

50 m/s variation). Baffle ring angle

and casing thickness

mainly affect fragment dispersion

causing velocity changes exceeding 200 m/s and dispersion angle variations up to 200%

while negligibly impacting EFP formation. The number of initiation points

significantly affects EFP performance

increasing head velocity by over300m/s and aspect ratio by approximately 30%

but has minimal effecton fragment velocity and only moderately influences dispersion angle. For axial EFP/preformed fragment composites

EFP exhibits high independence and is mainly governed by liner structure and initiation mode. In contrast

fragment dispersion involves complex interactions

collisions and energy exchange between tungsten spheres

requiring coupled design. Verified tests confirm that the composite warhead generates a high-speed projectile(1950m/s) along the axis and a tungsten sphere array with a dispersion velocity of700–830 m/s within a 0.543°–7.48° spread

capable of penetrating an 8 mm steel plate at 5 m.The results of this study provide valuable
