| 摘 要： | 采用显式有限元程序对聚能射流引爆裸露和带壳装药的过程进行了数值模拟分析。分析了射流引爆裸露装药和带壳装药两者间的不同作用过程,对射流引爆炸药的现象进行了探讨。结果表明,聚能射流引爆裸露装药取决于射流本身特性参数,而引爆带壳装药则与壳体性质密切相关。

| Abstract: | Advantage of explicit finite element method is take to simulate the ignition process of naked and confined charges by shaped charge. The different functions between naked and confined charges ignited by shaped charge jet are analyzed in the contexts. The ignition phenomena of stimulated explosives by shaped charge jet are also discussed. The results indicate that naked charge ignited by shaped charge jet depends on the characteristic parameters of the jet, while confined charge ignited by shaped charge jet ... |
