摘要:
以双响爆响药为研究对象，分别保持高氯酸钾、硝酸钾、铝粉和硫磺4种组分的质量不变，改变铝镁合金粉的质量分数,共得到20组配方。使用双通道声学分析仪，测定不同配方的声级值。定量研究了双响爆响药燃放声级随其混合物中铝镁合金粉质量分数变化的规律。实验结果表明，双响爆响药配方中铝镁合金粉的质量分数在20%~45%范围内能达到较好的燃放效果，铝镁合金粉的质量分数为35%时，爆响药燃放后的声级最大。
Abstract:
20 formulas were designed for the second bang powder of double-bang firecracker in this study by adding different mass fraction of Al-Mg alloy powder into a constant amount of mixture of potassium perchlorate, potassium nitrate, aluminum powder and sulfur. Dual-channel acoustic analysis was used to measure sound level for different formulas. A quantitative study was carried out on the sound level changes due to mass fraction verification of Al-Mg alloy powder in second bang powder of double-bang firecracker. The experimental results showed a fairly good firecracker display effect at a mass fraction range of Al-Mg alloy powder from 20% to 45% and a highest sound level at 35%.
