摘　　要：通过水下爆炸实验测定了不同铝氧比炸药的水下爆炸参数和能量参数,分析了铝氧比对该炸药体系冲击波峰值压力、比冲击波能、比气泡能以及能量输出结构的影响,拟合了铝氧比与能量输出结构的关系。结果表明,随着铝氧比的增加,炸药的峰值超压逐渐减小,比冲击波能先增大后减小,铝氧比约为0.3时达最大,比气泡能和气泡脉动周期均一直增大;比冲击波能所占总能量的比例减小,比气泡能比例先增加后减小;控制铝氧比为0.6左右时,炸药的能量利用率最高。The underwater explosion parameters and energy parameters of DNTF/AP/Al explosives with different Al/O ratios were determined by underwater explosion tests.The effects of Al/O ratio on the shock wave peak pressure,specific shock wave energy,specific bubble energy and energy output configuration of this explosive system were analyzed.The relations of Al/O ratio and energy output configuration were fitted.The results show that with increasing the Al/O ratio,the shock wave peak pressure decreases,specific shock wave energy increases first and then decreases and reachs maximum when Al/O ratio is about 0.3,the specific bubble energy and the period of the bubble pulsations increases throughout.The proportion of specific shock wave energy to total energy decreases,specific bubble energy proportion increases first and then decreases.The highest energy efficiency can be obtained by controlling Al/O ratio as about 0.6.
