为了对比奥克托今(HMX)基和三氨基三硝基苯(TATB)基高聚物粘结(PBX)炸药冲击起爆爆轰建立过程的差异,研究高能钝感炸药的爆轰成长特性,采用火炮驱动铝飞片实现平面冲击加载,建立一维拉格朗日锰铜压阻实验测试系统,得到高能PBXC03(以HMX为主)和高能钝感PBXC10(以TATB为主)炸药冲击起爆爆轰成长过程的不同拉格朗日位置处压力变化历史和前导冲击波时程曲线。结果表明:高能钝感PBXC10炸药的爆轰建立过程与高能PBXC03炸药明显不同,HMX基和TATB基PBX炸药冲击起爆和爆轰成长的物理机制存在较大差异。基于所得数据可标定高能钝感PBX炸药的反应速率方程。 |

In order to study the difference between detonation processes of HMX-based and TATB-based plastic bonded explosives and know more about the detonation growth characteristics of insensitive high energy explosives, an one-dimensional Lagrangian experimental test system is built based on manganin piezoresistive pressure gauge measurement technique, in which the aluminum flyers are used for planar impact loading. The impact initiation experiments are performed for PBXC03 (mainly HMX) and PBXC10 (mainly TATB) explosives. The pressure histories at different Lagrangian locations and the time-distance curve of shock front are obtained through experiment. The results show that the detonation growth progress of PBXC10 explosives distinctly distinguishes from that of PBXC03 explosives. This indicates that the physical mechanism of the shock initiation and detonation growth of HMX-based plastic bonded explosives is different from that of TATB-based plastic bonded explosives. The experimental data can be used to calibrate the reaction rate equation of insensitive high energy explosives. |
