| 摘 要： | 采用铝基组合式电磁粒子速度计技术，通过一维平面冲击实验研究了JB-9014炸药的冲击起爆反应增长规律，获得了11.33～14.18 GPa不同初始入射冲击压力下JB-9014炸药撞击界面及其内部不同深度处冲击前沿的波后粒子速度，进而得到粒子速度-时间波剖面图，并拟合得到未反应JB-9014炸药的Hugoniot关系。此外，根据冲击波跟踪器所测波形获得了不同冲击压力下的到爆轰时间及距离。

| Abstract: | To find out about the patterns and regularities of the reaction growth of shock initiation on JB-9014 explosives, using aluminum-based multiple EMV, we conducted six one-dimensional planar impact experiments in the gun-power platform. Under different initial pressures (11.33?14.18 GPa), we measured the particle velocity versus time up(t) and wave-profiles in the JB-9014 explosive at 9 different distances from the impact plane, and recorded the position of the shock front with time x(t), successfully fitting the unreacted explosive JB-9014 Hugoniot relation. Furthermore, we obtained the time and distance to detonation are estimated according to both the wave-profiles and the x(t) trajectories from the shock wave tracker gauges. |
