摘要
为分析定向式动能杆战斗部在不同装药结构下的抛撒规律,以非线性动力分析软件LS-DYNA为工具,应用ALE算法,对定向式动能杆战斗部在不同的装药宽度、装药厚度下进行了数值模拟,得到了装药宽度、厚度对杆条飞散速度和抛撒角度的影响规律,模拟结果与文献中实验得到的规律基本一致,为此类战斗部的设计提供了参考。
In order to study the rules of directed kinetic-rod with different structure of dynamite, by employing ALE of arithmetic, the different directed kinetic-rod warheads are simulated with non-linear and dynamic finite program of LS-DYNA. The influence rules of the width and thickness of explosive on the fly-off velocity and angel of the rods are analyzed, which are validated by the test results in the literature. The study provides reference for the warhead＇s design.
