| 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。

| Abstract: | A quasi-isentropic compression loading technique (ICE) driven by electro-magnetical was applied to investigate the dynamic behaviors of an un-reacted HMX based polymer-bonded explosive(PBX). Multiple samples with different thicknesses were loaded up to 8 GPa. Particle velocities of the interface between sample and LiF windows were measured by laser interference method, and by Lagrange data processing, the experimental isentropes within 8 GPa of this explosive were obtained. Based on the fitting parameters of the isentropes, the isentropic compression procedure was numerically simulated by one dimensional hydrodynamics code, and the calculated particle velocities are consistent with the experimental results. |
