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 wedgeshaped 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 ...
