摘要
针对传统多模战斗部只能产生EFP/JPC,或JPC/JET两种毁伤元的问题,为了实现同一战斗部能产生EFP/JPC/JET三种毁伤元,提出了一种新型多模战斗部装药结构,通过前置装药和预留装药空间的方式,改变了传统装药结构和药型罩结构,并采取对前置装药和主装药间隔起爆时间的控制。通过LS-DYNA数值模拟,获得了EFP,JPC和JET三类毁伤元。其中,EFP、JPC、JET的头部速度分别为3573 m/s,5062 m/s,6342 m/s;尾部速度分别为1756 m/s,1345 m/s,-276 m/s;从数值模拟的角度论证了该毁伤元转换技术的可行性。
Aimed at the traditional multimode warhead can only produce two kinds of damage elements which are EFP/JPC or JPC/JET,and in order to realize the goal that the same warhead can produce three kinds of damage elements which are EFP/JPC/JET,a new multimode warhead charging structure is proposed in this research,through pre-charging and reserving charge space,which changes the traditional charging structure and liner structure. Also,the interval between the pre-charge and the main charge initiation is controlled. Three kinds of damage elements（ EFP,JPC and JET） are obtained by LSDYNA numerical simulation. The head speed of EFP,JPC and JET is 3573 m/s,5062 m/s,6342 m/s,and the tail speed is 1756 m/s,1345 m/s,-276 m/s,respectively. The feasibility of the damage element transformation technology is demonstrated from the prospective of numerical simulation.
