| 摘 要： | 带尾翼的杆状爆炸成形侵彻体(explosively formed penetrator,简称EFP)具有良好的飞行稳定性和侵彻性能.在对能形成该种类型EFP的战斗部结构形式进行分析的基础上,以两种典型的结构形式(异形壳体和多点起爆)为例,采用AUTODYN-3D软件进行了EFP成形的三维数值模拟,得到了尾部带有不同形状尾翼的爆炸成形侵彻体.计算结果对于EFP战斗部的设计具有重要的参考价值.

| Abstract: | An explosively formed penetrator (EFP) with fins has the advantages of stable flight and deep penetration. On the basis of analyzing several possible approaches to form an EFP with fins, a three dimensional numerical simulation using the AUTODYN 3D software was carried out on two typical structures including special cases and multi point ignition. Then, EFPs with satisfactory shapes were obtained. The calculation results can be used in the design of EFP warheads. |
