摘　　要：为实现“一弹多用”的战术目的,提出一种多模战斗部。战斗部外层采用高爆速炸药、内层采用低爆速炸药的复合聚能装药结构,通过改变起爆点的位置,改变作用于药型罩的爆轰波形状,并利用ANSYS/LS-DYNA数值模拟软件研究内、外药型罩罩顶壁厚匹配对PELE/EFP多模毁伤元成型及侵彻性能的影响规律。结果表明:带隔板聚能装药结构可有效实现PELE/EFP多模毁伤元的转换,当外层药型罩罩顶壁厚为0.037CD时,多模毁伤元成型及侵彻效果最优。In order to achieve the tactical purpose of“one projectile multi-purpose”,a multi-mode warhead is proposed.The warhead adopts a composite shaped charge structure with high detonation velocity explosives in the outer layer and low detonation velocity explosives in the inner layer.By changing the position of the initiation point,the shape of detonation wave acting on the liner is changed.At the same time,ANSYS/LS-DYNA numerical simulation software is used to study the influence of top wall thickness matching of inner and outer liner on PELE/EFP multi-mode damage element forming and penetration performance.The results show that the PELE/EFP multi-mode damage element can be converted effectively by the shaped charge structure with separator.When the top wall thickness of the outer liner is 0.037CD,the forming and penetration effect of the multi-mode damage element is the best.
