JB-9001钝感炸药冲击Hugoniot关系测试

 利用“压力对比法”实验技术，通过锰铜压力计测试待测炸药样品和LY12铝样品在LY12铝飞片的同时撞击下的界面压力p_exp和p_Al，从冲击波关系式和正交回归直线拟合分析，确定了JB-9001钝感炸药的冲击Hugoniot关系。

Shock Hugoniot Relation of JB-9001 Insensitive High Explosive

Shock Hugoniot relation is the basic characteristic parameters of explosive. JB-9001 is a plastic bonded explosive which mainly contains TATB. JB-9001 explosive and standard material LY12 samples were processed and their sizes are same. Two samples are symmetrically put on the LY12 base plate. One dimensional detonation loading system consists of detonator, initiation charge, plane wave generator and main charge. The LY12 flyer is driven by detonation wave which is attenuated with a metal plate. We use manganin gauges and oscilloscope to record the interface pressure p_exp and p_Al between the LY12 base plate and the explosive sample as well as between the LY12 plate and LY12 sample. Since the shock Hugoniot relation of LY12 is known, we can determine a reflected shock Hugoniot relation curve on the Hugoniot diagram by measuring the interface pressure p_Al. On the basis of the shock wave formula and boundary conditions, the shock wave velocity u_s and the particle velocity u_p behind the wave are derived. We have obtained the shock Hugoniot relation of JB-9001 explosive with average density ρ₀=1.875 g/cm³ by using least square method u_s=(2.78±0.21)+(1.43±0.19)u_p (0.40 km/s≤u_p≤1.51 km/s) experimental measuring error is less than 5%.
