| 摘 要： | 采用双灵敏度VISAR对JB-9014炸药在20 GPa的球面散心冲击波作用下冲击引爆过程开展了实验研究。测得的不同厚度JB-9014炸药/窗口界面的粒子速度历程表明,到爆轰距离为2~3 mm,在3~5mm处反应冲击波已发展为稳定爆轰波。开展了相应的初步数值计算工作,计算结果与实验基本吻合。

| Abstract: | By bi-sensitivity VISAR,the shock initiation of JB9014 under divergent spherical shock wave(20 GPa) was experimentally studied.The particle velocity profiles of explosive/window interfaces at different positions were measured.The results show that the run to detonation is within 2~3 mm,and steady detonation is fully developed at 3~5 mm.Preliminary modeling was carried out with hydrocode.The simulation is in accordance with the experimental results. |
