导引头对射流破甲威力的影响研究

Influence of Seeker on Penetration Power of Jet

利用LSDYNA有限元分析软件数值模拟了单锥罩、弧锥罩和双锥罩对导引头和目标靶板的毁伤效应。通过改变导引头与药型罩的两者间距,分析了导引头的空间位置对射流的影响,以及导引头的影响程度随药型罩锥角的变化趋势。结果表明,导引头与药型罩的距离为药型罩口径的0. 5倍时,射流成型具有基本的空间条件以保证破甲威力;在导引头的干扰存在下,大锥角药型罩形成的射流破甲能力更强。

The damage effects of single-cone liner,arc-cone liner and biconical liner on seeker and target plate were simulated by LSDYNA finite element analysis software.By changing the distance between the seeker and liner,the influence of the space position of the seeker on the jet and the change trend of the influence degree of the seeker with the change of the cone angle of the liner were analyzed.The results show that when the distance between the seeker and the liner is 0.5 times of the liner’s diameter,the jet forming has basic space condition to ensure the penetration power.Under the interference of the seeker,the penetration power of jet with the large cone liner is stronger.
