摘要
利用磁驱动准等熵压缩加载实验技术,研究了某奥克托今(HMX)基高聚物粘结炸药(PBX)未反应固体炸药峰值压力8 GPa内的动力学响应特点。实验在保持多样品加载压力历史一致的前提下,同时加载多个不同厚度实验样品,用激光干涉测速方法获得了样品的速度响应历史曲线,对实验数据进行了Lagrange分析处理,获得了该PBX炸药样品8 GPa内的准等熵压缩线,多发实验获得的准等熵压缩线在该压力范围内一致,基于该状态方程的拟合参数对实验结果进行了流体动力学计算,计算结果与实验结果吻合较好。
A quasi-isentropic compression loading technique（ IC E） driven by electro-magnetical w as applied to investigate the dynamic behaviors of an un-reacted HM X based polymer-bonded explosive（ PBX）. M ultiple samples w ith different thicknesses w ere loaded up to 8GPa. Particle velocities of the interface betw een sample and LiF w indow s w ere measured by laser interference method,and by Lagrange data processing,the experimental isentropes w ithin 8 GPa of this explosive w ere obtained. Based on the fitting parameters of the isentropes,the isentropic compression procedure w as numerically simulated by one dimensional hydrodynamics code,and the calculated particle velocities are consistent w ith the experimental results.
