Experimental research on effects of porosity on shock initiation of PBX explosive

  • 摘要: 为了研究孔隙度(装药密度)对PBX炸药冲击起爆爆轰成长的影响,采用炸药冲击起爆锰铜压阻一维拉格朗日实验测试系统,测量了不同孔隙度的PBXC03炸药(HMX的质量分数为87%,TATB的质量分数为7%,黏结剂的质量分数为6%)冲击起爆过程不同拉格朗日位置的压力-时间历史。结果显示:在本文装药范围和加载条件下,孔隙度对PBX炸药冲击起爆爆轰过程的影响不单调,中等密度的炸药冲击起爆和爆轰成长最快,这是热点点火过程与燃烧反应过程共同作用的结果。
