摘要
为研究炸药对定向式动能杆飞散速度的影响规律,以非线性动力分析软件LS-DYNA为工具,分别对PENT,Deta sheet-C,C4炸药,TNT,B炸药和8701共6种不同炸药对定向式动能杆的飞散速度进行数值模拟研究,得出炸药的密度、爆速和爆压对动能杆飞散速度的影响规律。实验得到Detasheet-C装药下动能杆的飞散速度,仿真结果与试验结果基本吻合,可为此类战斗部的设计提供参考。
In order to research the effect of explosive on disperse velocity of directed KE-rod, six different sorts of explosive such as PENT, Detasheet-C, explosive C4, TNT, explosive B and 8701, were used by directed kinetic-rod warhead to make numerical simulation with the non-linear and dynamic finite program of LS-DYNA. The influence of explosive density, exploding speed and pressure on disperse velocity of KE-rod was analyzed. The KE-rod velocity of explosive Detasheet-C was obtained, and the numerical simulation agrees well with the experimental result. The result of numerical simulation can provide valuable reference for the design of KE-rod warhead.
