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 analyze the law of throwing of the directional kinetic energy bar warhead under different charge structures, a non-linear dynamic analysis software LS-DYNA was used as the tool. The effects of charge width and thickness on the flying speed and the throwing angle of the rod were obtained. The simulation results are in good agreement with those obtained in the literature, which provided a reference for the design of such warhead.
