摘　　要：利用LS-DYNA3D软件对钨铜粉末药型罩聚能射流的形成过程进行了数值模拟,采用多物质ALE算法,模拟了钨铜聚能射流的形成过程,并与实验结果进行了对比。结果表明,随着药型罩密度的增加,射流直径变细,头部速度降低,数值模拟结果与实验结果较一致。Formation process of the shaped charge jet of Tungsten-Copper powder liner was simulated through numerical method with the LS-DYNA3D software.With Multi-Material ALE Algorithm,the formation process of the shaped charge jet was simulated and compared with the experimental results.The results show that the jet diameters become thinner,the head jet speed reduces with the increase of liner density,and the simulation results and experimental results are consistent.
