摘　　要：随着防护技术的不断发展,现代舰船的抗爆炸冲击能力日益增强,而常规药型罩聚能鱼雷战斗部已很难对新型舰艇予以致命毁伤。为此,文中在圆锥、球缺组合药型罩聚能战斗部的基础上设计了一种双球缺组合药型罩聚能战斗部,分析了其作用机理,利用有限元软件ANSYS/LS-DYNA进行了数值仿真,得到了其侵彻带含水夹层圆柱壳靶板的应力云图。仿真结果表明,该战斗部利用前级小球缺罩形成的聚能射流能为后续大球缺罩形成的爆炸成型弹丸(EFP)随进破坏开辟通路,对目标的毁伤效应强于圆锥、球缺组合药型罩聚能战斗部。该研究结果可为新型高效鱼雷战斗部设计提供参考。With the development of protection technology,the anti-explosion and anti-shock ability of modern ship has been improved increasingly.However,the conventional shaped charge torpedo warhead with common liner is difficult to damage modern ship fatally.Therefore it is necessary to improve the power of torpedo warhead for damaging enemy ships.In this paper,a kind of shaped charge warhead with two spherical combined liners is proposed based on the shaped charge warhead with tapered and spherical combined liners.The structure of warhead is designed,its working mechanism is analyzed,and numerical simulation is performed with the finite element analysis software ANSYS/LS-DYNA.The stress contour of a cylindrical shell target with embedded water layer in its penetration zone is obtained.Simulation result shows that the warhead with two spherical combined liners can provide moving space for the latter explosively formed projectile(EFP)by making use of the former shaped charge jet,which leads to higher destructive effect on target than that of shaped charge warhead with tapered and spherical combined liners.This research may provide a reference for design of new high-powered torpedo warheads.
