Cook-off Test and Numerical Simulation of HMX-Based Cast Explosive Containing AP

  • 摘要: 为研究新型奥克托今(HMX)基浇注炸药GOLA-1(HMX-Al-高氯酸铵(AP)-黏结剂(Kel-F))在热刺激下的响应特性,对GOLA-1炸药进行了温升速率为1.0和1.5 K/min的烤燃实验,获得了炸药中心点温升和点火时间等信息。在此基础上,结合烤燃数值模拟,预测了炸药的点火位置及温度。数值模拟与实验结果吻合较好,在1.0和1.5 K/min温升速率下GOLA-1炸药点火时间的相对偏差分别为1.3%和1.7%,表明所建立的数值模型较为合理。采用该模型进行了不同温升速率下的数值模拟,结果表明:当温升速率下降至0.4 K/min时,点火位置由装药底面边缘的环形区域移动至装药中心轴线上靠近下部的位置;点火位置随温升速率的下降而逐渐向药柱上部移动,温升速率对点火温度基本没有影响。
