水下爆炸冲击波能的数值计算

Numeration of Shock Wave Energy for Underwater Explosion

在进行炸药配方设计时,冲击波能的计算是非常重要的。理想炸药水下爆炸的冲击波能流密度符合爆炸相似率。提出了方程中系数ζ和γ的计算公式,参数ζ和γ可以通过炸药的爆热、爆压和密度等近似计算。根据文献值拟合冲击波能随铝氧比的变化公式,可用来计算非理想炸药的冲击波能。计算结果与试验数据吻合较好。

Calculating shock wave energy is very important in the process of explosive design. Energy flux density of ideal explosive follows explosion similar rules. A formula which contains parameters such as explosion heat（ Qx ） , explosion pressure （Pd） and density（ρ） are put forward to calculate ζ and γ,and an equation about shock wave energy versus Al/O is deduced. The equation is suitable to calculate shock energy of non-ldeal explosives. The results are very consistent with experimental data.
