摘　　要：采用激光干涉测速技术和楔形炸药,对未反应钝感高能炸药JBO-9021的冲击雨贡纽曲线进行了实验研究。通过激光干涉测试技术对楔形炸药冲击波后不同位置的多点粒子速度进行测试,获得一组不同压力下未反应炸药中的波后粒子速度和冲击波速度,通过曲线拟合得到未反应炸药的冲击雨贡纽曲线。同时将未反应炸药的冲击雨贡纽曲线和冲击波阵面的Rankine-Hugoniot关系进行联立,获得未反应炸药的状态方程。Laser interferometry for measuring velocities and wedge-shaped test explosive were used to study the Hugoniot of unreacted insensitive high explosive JBO-9021 and, on the basis of the wedge- shaped design, the velocities of the particles and the shock wave under different pressures were obtained from the experiment by measuring the particles＇ velocities at different positions of the test explosive. Based on the experiment data achieved,the Hugoniot parameters of the unreacted JBO-9021 explosive were derived from our theoretical analysis and non-linear interpolation. Moreover, the equation of state of the unreacted insensitive high explosive JBO-9021 was also derived from the simultaneous equations of the Hugoniot relation and Rankine-Hugoniot relationship of the shock wave front.
