| 摘 要： | 采用Hybrid反应率结合修正的JWL方程，研究了LX-17、超细TATB等钝感炸药的冲击起爆（SDT）过程，并计算了爆轰波的对碰现象。结果表明，该方法计算钝感炸药的冲击起爆过程与实验数据符合较好；计算爆轰波对碰区的峰值压力提高了10％。

| Abstract: | The shocking-to-detonation transition(SDT) of insensitive high explosives(IHE) including LX-17 and ultrafine TATB was studied by using Hybrid reaction rate model and modified JWL equation of state(EOS),and phenomena of colliding diverging detonation was numerically simulated.The calculated shocking-to-detonation transition(SDT) of insensitive high explosives is in agreement with the experimental result,and the calculated peak pressure in colliding diverging detonation increases 10%. |

| Keywords: | mechanics of explosion overdriven detonation shocking-to-detonation transition insensitive high explosive |
