| 摘 要： | 为了研究BNCP驱动飞片的能力,采用光纤位移干涉仪(DISAR)对其速度进行了测试,获得了速度成长曲线.测试结果显示:当BNCP在1.645g/cm3和1.623 g/cm3密度下驱动0.1 mm厚的钛飞片时,飞片速度分别可达3400m/s和3 300m/s左右.同时,通过VLW状态方程程序计算了BNCP的等熵膨胀数据,拟合出其JWL状态方程参数.将JWL状态方程参数运用于软件LS-DYNA中,对BNCP驱动飞片进行数值模拟.结果显示数值模拟与实验曲线基本一致.

| Abstract: | In order to study the ability of BNCP driving flyers,the flyer velocity under different density of charge condition were investigated by DISAR.The results showed that the velocity of flyer driven by BNCP with 1.645g/cm3and 1.623 g/cm3 could reach to 3 400m/s and 3 300m/s approximately.The coefficients of the JWL equation of state were fitted by the isentropic expansion data calculated by VLW code,then the flyer velocity were simulated by inputting the coefficients of the JWL EOS to LS-DYNA.It showed that the numerical simulation results were in accordance with the experimental results. |
