摘要

为进一步提高爆炸成型侵彻体战斗部的毁伤能力,采用理论分析、数值仿真和试验验证的方法,设计了一种爆炸成型箭形侵彻体战斗部。通过设计条形药型罩横行排布时的排布数量控制爆炸成型箭形侵彻体的成型效果,提高毁伤元的毁伤威力。以理论分析,建立物理模型,确定条形药型罩的罩横向排布数量,通过数值仿真验证设计方案可行性,进而制备出了条形药型罩横向排布数量为12的战斗部,并进行静爆试验,试验结果表明,单枚条形药型罩可成型为2枚爆炸成型箭形侵彻体,可穿透5 m处30 mm厚的Q235钢板。研究结论对爆炸成型毁伤元战斗部的设计具有重要意义。

Abstract

In order to further enhance the damage capability of the explosively formed penetrator (EFP) warhead, a combination of theoretical analysis, numerical simulation, and experimental verification was employed to design a novel explosively formed arrow-shaped penetrator warhead. The formation effect of the explosively formed arrow-shaped penetrator was controlled by adjusting the number of linearly arranged explosive liners, thereby increasing the damage power of the damage element. Initially, theoretical analysis was conducted to establish a physical model, determining the number of liner arrangements. Subsequently, numerical simulations were performed to validate the feasibility of the designed scheme. A warhead with 12 columns of linearly arranged liners was then fabricated and subjected to static detonation experiments. The experimental results demonstrated that a single liner could form two explosively formed arrow-shaped penetrators, capable of penetrating a 30 mm-thick Q235 steel plate at a distance of 5 m. The research findings indicate that the principle of forming explosively formed arrow-shaped penetrators from linear liners is viable and holds significant implications for the design of EFP warheads.

Key words： warhead; explosively formed; flechette penetrator
