| 摘 要： | 运用ANSYS/LS-DYNA仿真软件,采用中心点起爆和环形起爆的方式,对多模战斗部球缺型药型罩进行结构优化设计。选取球缺型药型罩结构参数曲率半径和壁厚仿真进行仿真计算,并对计算结果进行了Matlab三维作图分析。找出了形成多模毁伤元EFP和JPC最优区间所对应的药型罩结构参数范围,其中药型罩曲率半径取0.7～0.9倍装药口径。药型罩壁厚取0.40～0.56倍装药口径。进行了多模毁伤元成型试验研究,试验结果与仿真结果较一致,为今后进一步研究多模战斗部提供了参考依据。 |

| Abstract: | Through using center initiation and annulus initiation ,the configuration of hemispherical liner of multimode warhead was optimized and designed by ANSYS/LS-DYNA software. Choosing numerical simulation project of curvature radius and thickness of hemispherical liner and analyzing the result, the range of configuration parameters of hemispherical liner to form preferable EFP and JPC penetrators was received by three-dimensional chart analysis with matlab,when curvature radius of liner was 0.7~0.9 times charge caliber, thickness of liner was 0.40~0.56 times charge caliber,the formation of multimode penetrators was accorded with the trial item desire. |
| Keywords: | Multimode warhead Hemispherical liner Explosively Formed Penetrator(EFP) Jetting Penetrator Charge(JPC) Numerical Simulation |
