摘要
运用AUTODYN软件,对壳体外刻槽的预控破片战斗部在不同槽深和槽宽时的破片形成过程进行数值模拟,对比分析了仿真结果,得出了槽深和槽宽对预控破片的有效破片生成率、破片平均速度和破片质量损耗的影响规律,并通过综合分析,得出比较合适的槽深和槽宽。
By use of AUTODYN, the numerical simulation of the fragment formation of preformed fragment warhead, which external shell groove has different groove depth and width parameters, was carried out. After comparing and analyzing the simulation results, the effect rules of groove depth and width on the effective formation rate ofpreforrned fragment, average speed of fragment and mass loss were found out, thus the suitable groove width and deoth were determined.
