JO-9159炸药强爆轰雨贡纽实验及产物的状态方程研究

Research on the Hugoniot Experiment and EOS of Product for JO-9159 Explosive Overdriven Detonation

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JWL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JWL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。

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 explosive were obtained by the antitheses method.The overdriven detonation state of explosive was described by a combination equation of JWL andγ.The parameter values of equation of state（EOS）of overdriven detonation products 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 JWL and γ.
