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.
