| 摘 要： | 在药型罩上粘附铝隔板是一种新的形成尾翼型爆炸成型弹丸（Explosively Formed Projectile,EFP）的实验方法。通过实验和数值模拟对该方法进行了分析,探讨了形成尾翼的机理。利用有限元分析软件LS-DYNA,对大锥角型、球缺型和弧锥结合型3种不同药型罩在采用新方法时形成的尾翼型EFP进行了三维数值模拟分析,并将模拟结果与实验结果进行对比。研究结果表明：3种药型罩均能形成比较明显的尾翼,数值计算结果与实验结果较吻合。该研究为设计尾翼型EFP提供了一种新的参考方法。

| Abstract: | It is a new method to produce an explosively formed projectile (EFP) with fins by attaching aluminumcover on the liner.Experi mental and numerical research were performed using this new method.Furthermore,the mechanism of forming fins was discussed.The new method of forming EFP with fins was si mulated by LS-DYNA,and a contrastive analysis was carried out on three typical liners,including big-cone shaped,i mperfect-sphere shaped and arc-cone shaped.The results from 3D numerical si mulations and experi ments... |
