摘要
文中采用电测法对密度为1.0～1.5 g/cm3的装药爆炸产生的冲击波参数进行了实验研究。分析测试结果得到了冲击波参数与装药密度的关系曲线及回归系数,并与经验公式计算结果进行了比较。结果表明,当ρ在1.5 g/cm3时Δpm、t+、i+实测数值与经验公式计算结果相符,此外还得出了t-、tr、θ与装药密度的关系,对进一步探讨冲击波特征有一定参考价值。
Based on the electrical measurement method the air shock-wave parameters generated by explosives whose densities ranged from 1.0 g/cm^3to 1.5 g/cm^3 were studied by experiments. The relationship curves and the regression coefficients between the parameters of the air shock-wave and the charging densities are obtained based on the testing results. When compared with the empirical formulas calculations, the results show that the testing values of △ρ,, t ＋, i＋ are consistent with the calculations when the charging density is 1.5g/cm^3. Besides, the relationships between t- 、tr、 θ and the charging density are also gained, which will be the valuable reference for the further exploration of the characteristics of the shock waves.
