| 摘 要： | 对六硝基六氮杂异伍兹烷(CL-20)基压装混合炸药爆轰产物JWL状态方程参数进行了研究。采用直径25mm标准圆筒试验研究了CL-20基压装炸药(C-1,CL-20/钝感粘结剂(质量比)=94.5/5.5)的驱动做功能力,获得了圆筒壁膨胀速度、位移与时间的关系;应用考虑与爆轰参数封闭的炸药JWL状态方程参数数据处理方法得到该炸药的JWL状态方程参数,应用参数进行圆筒模型数值模拟,与试验结果对比,发现速度误差低于2%,位移误差低于1%;对比了本研究参数与国外类似炸药参数在做功能力上的差异,结果表明,LX-19和PBXC-19的格尼速度比C-1炸药分别高2.02%和2.20%。 |

| Abstract: | The JWL equation of state of detonation product for pressed composite explosive based on CL-20 was studied. The driving ability for C-1 explosive(mass ratio: CL-20/insensitive binder=94.5/5.5) was evaluated by 25mm standard cylinder test, and the relationships between expansion velocity/displacement of the cylinder wall and time were analyzed. Under the consideration of the equation close, the JWL equation parameters were obtained by the data processing method. And using these parameters, the cylinder tests for reference explosives LX-19,PBXC-19 were simulated, and the driving ability of the C-1 and LX-19,PBXC-19 were also analyzed. Results show that the relative error of velocity and displacement between the simulation and experiment are less than 2% and 1%, respectively. Compared with LX-19 and PBXC-19, gurney velocity of C-1 increases 2.02%, 2.20%, respectively. |
