【摘要】 在国内外学者研究基础上分析了不同头部形状及不同材料射弹对裸装炸药的引爆判据,利用数值模拟计算得到了不同射弹材料、射弹头部形状对引爆状态的影响结果,进而提出了综合考虑射弹头部形状及材料密度的射弹冲击引爆炸药临界条件经验表达式。与已有试验结果相比较,该表达式能较好的描述裸装炸药在承受冲击条件下的起爆响应。更多还原

【Abstract】 Initiation criterion of different nose shape and different material of projectile has been studied base on research result of other scholars in this paper.The inference result of different projectile parameters has been got using numerical simulation and a new experiential expression has been established which include the effect of nose shape and material of projectile.Compare with the corresponding experiments result,the expression describe the shock response truly as projectile impact into high explosive.更多还原
