JO-9159炸药强爆轰雨贡纽实验及产物的状态方程研究

摘要

The propagation velocity of the shock wave in the JO-9159 explosive sample and the aluminum sample was detected by a high-speed scanning camera.Hugoniot relations of the overdriven detonation product of JO-9159 ex-plosive were obtained by the antitheses method.The overdriven detonation state of explosive was described by a combination equation of J WL andγ.The parameter values of equation of state (EOS)of overdriven detonation prod-ucts for JO-9159 explosive were determined based on the experiment results.The results indicate that the p-V curve of the EOS is well consistent with the experimental results.The overdriven detonation state of explosive may be more accurately described by the combination equation of J WL andγ.%采用高速扫描相机测量冲击波在JO-9159炸药试样和铝试样中的传播速度，用对比法得到JO-9159炸药强爆轰产物的雨贡纽关系。采用J WL与γ的联合方程描述炸药强爆轰产物的状态，基于实验结果确定了其状态方程的参数值。结果表明，该状态方程的p－V曲线与实验结果吻合较好。用J WL与γ律联合方程可较准确地描述JO-9159炸药强爆轰产物的状态。
