为研究药型罩锥角和壁厚对多爆炸成型弹丸成型的影响,利用ANSYS/LS-DYNA软件对多爆炸成型弹丸的成型过程进行数值模拟。研究结果表明:多爆炸成型弹丸中心处药型罩锥角采用130°~140°、边缘处药型罩锥角采用145°~155°、药型罩壁厚采用2.5~3.5mm时,其侵彻性能较好。研究结果可为多爆炸成型弹丸的设计提供参考。

In order to study the effects of cone angle and thickness of liner on the formation of multiple explosively formed projectile (MEFP), the warhead is designed to produce seven explosively formed projectiles(EFP). ANSYS/LS-DYNA software is used to simulate the formation process of MEFP. The research result shows that the cone angle of the central liner is suitable for 130°~ 140°, and the cone angle of the marginal liner is fit for 145°~155°, the penetration effectiveness of EFP is better on the basis of the thickness of liner selected between 2.5mm and 3.5mm. The result provides the reference for the design of MEFP.
