The simulation results are basically consistent with those in the literature, and differ slightly with those obtained by experiments. The simulation results can provide a reference for the design of this type of warhead., authors=WANG Yingchun, WANG Jie, WANG Kun, authorsList=WANG Yingchun;WANG Jie;WANG Kun, authorCompany=Air

runingTitle=null, highlight=null, articleAbstract=为研究长径比对定向式动能杆飞散特性的影响规律,以非线性动力分析软件LS-DYNA为工具,分别对11种不同长径比的动能杆进行数值模拟,得出动能杆飞散速度、空间分布与动能杆长径比的关系：当长径比大于5小于11时,动能杆的速度呈递增趋势,当长径比大于11时,动能杆的速度趋于平缓,有所降低;从空间分布看,长径比大于5小于8时,动能杆的空间分布较密集,长径比大于8时,动能杆的空间分布相对散开,分布也均匀,当长径比为11时,动能杆的飞散速度和空间分布最优.和文献中的数据进行对比,仿真与文献中数值计算结果基本吻合,和实验稍有差距,可能是由数值模拟采用的材料模型和试验所用的材料有一定误差所致.仿真结果可为此类战斗部的设计提供参考.,
