Abstract:

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25 mm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%
