摘要/Abstract

摘要： 起爆方式对双层药型罩爆炸成型弹丸（EFP）成型特征参数及终点毁伤效应具有重要影响。基于双层药型罩EFP战斗部静爆试验结果，利用ANSYS/LS-DYNA非线性有限元动力学软件研究了起爆点数目对双层药型罩EFP战斗部成型及侵彻特性的影响规律。研究结果表明：当起爆点数目在4～8时，双层药型罩EFP战斗部可起爆成型具有良好空气动力学特性及优良终点毁伤效应的带尾翼大长径比聚能侵彻体；当起爆点数目为6时，双层药型罩EFP战斗部成型侵彻体终点毁伤效应的最大侵彻深度达到1.07倍的装药口径，较端面单点中心起爆方式获得侵彻体侵彻钢靶的最大深度提高了32%.

Abstract: Initiation modes have important influence on formation and penetration of double-layer liners explosively-formed projectile (EFP). Based on the experimental study of double-layer liners EFP warhead, the effect of multi-point initiation on the formation and penetration of EFP warhead with double-layer liners is analyzed by using ANSYS/LS-DYNA software. Results show that the EFP warhead with double-layer liners can form a large aspect ratio of L/D(the length/diameter) penetrator with good flight characteristics and terminal effects when the number of initiation points are between 4 and 8. As the number of initiation points reach 6, the maximum penetration depth is about 1.07 times of the charge diameter which is increased by 32% compared with an initiation point in the same shape charge structure. The conclusions can supply a theoretical reference for choosing the appropriate initiation point parameters of the double-layer liners EFP warhead.
