| 摘 要： | 针对地雷的毁伤目标和特性,提出一种新颖的多棱柱状药型罩结构,其可看作由八个楔形罩对称排列相邻连接而成.应用非线性有限元软件完成了爆炸载荷下多棱柱状药型罩形成射流过程的数值模拟,结果表明新型药型罩结构能够实现预期设想,形成一股汇聚射流.研究结果为地雷战斗部研究提供了一种新的选择.

| Abstract: | A new multi-row cylindrical liner structure was proposed against the penetrating targets and characteristics of mine.It can be seen as 8 symmetrical cuneiform liners connecting each other.The process of the multi-row cylindrical liner forming jet flow under explosion load was simulated by nonlinear finite element software.The results show that the new liner could form jet flow,which realized expected imagination.The research results can provide a new selection for study on mine warhead. |
