摘　　要：对HMX基含铝炸药进行了自由场爆炸试验,通过理论计算和仪器测量获得了爆炸冲击波参数和火球热效应数据.依据爆炸效应,提出了一种针对含铝炸药爆炸威力的评价方法.结果显示,在试验范围内,相比TNT炸药,该含铝炸药的冲击波超压(Δp)和冲量(I)在最大处分别提高了33.1% 和28.9%;火球的温度、尺寸也更高、更大,在高温区域(温度大于2000℃),该含铝炸药的温度持续时间是TNT的7倍;提出的对含铝炸药爆炸威力评价的方法更能精确揭示含铝炸药的综合爆炸性能,该方法也可以应用到其他相似含铝炸药爆炸威力的评价上.The explosion experiments of cyclotetramethylene tetranitramine(HMX)based aluminized explosive(AE)were carried out in free filed.The shock wave parameters and heat effect data were obtained through theoretical calculation and instrument acquisition.Based on the explosion effects,a method for evaluating the power of AE was proposed.Results show that,in the experimental range,the overpressure(Δp)and impulse(I)of AE increase by 33.1%and 28.9%respectively compared with those of TNT in the largest position.The explosion fireball temperature and dimension are also much higher and greater,in high temperature range(greater than 2000℃),and the duration of AE is 7 times that of TNT.The method for evaluating the power of AE is more accurate to express its comprehensive power and helpful to compare the power of other similar non-ideal explosives.
