摘要

为提升聚能装药战斗部的侵彻能力,提出了一种隔板-药型罩贴合式聚能装药结构。为探究药型罩结构参数对射流头部速度及射流侵彻能力的影响规律,采用 LS-DYNA 有限元软件对隔板-药型罩贴合式聚能装药结构进行数值模拟分析。研究结果表明:射流的极限侵彻深度随药型罩圆柱部宽度的增大先增高后降低,随药型罩圆柱部高度的增加而增高。在炸高为2.5倍装药直径的情况下,药型罩圆柱部高度为14 mm,圆柱部宽度为18 mm可以实现最优侵彻效果,对45#钢靶的极限侵深为478.1 mm,触靶速度可达13 650 m/s。

Abstract

In order to enhance the penetration capability of the shaped charge warhead, a shaped charge with waveshaper-liner linked was proposed. To investigate the influence of the structural parameters of the propellant cover on the velocity of the jet head and the penetration ability of the jet, LS-DYNA finite element software was used to numerically simulate the structure of the shaped charge with waveshaper-liner linked. The research results indicate that the maximum penetration depth of the jet increases first and then decreases with the increase of the width of the cylindrical part of the propellant cover, and increases with the increase of the height of the cylindrical part of the propellant cover. When the explosive height is 2.5 times the diameter of the charge, the optimal penetration effect can be achieved by having a cylindrical height of 14 mm and a cylindrical width of 18 mm for the shaped charge cover. The maximum penetration depth for the 45 # steel target is 478.1 mm, and the contact speed can reach 13 650 m/s. The research results have certain guiding significance for the design of concentrated energy warheads.
