钛基纤维炸药水下爆炸性能的初步分析

摘要

In this study we examined the changing tendency of the shock wave energy,bubble energy,total energy per unit mass and the total energy per unit volume by analysis of the pressure-time curves,and analyzed the chemical reaction process of the Ti fiber explosive through the total energy per unit mass.The results show that the peak pressure and the shock wave energy of the Ti fiber explosive per unit decreases as the Ti fiber content increases,the bubble energy per unit mass increases with the increase of the Ti fiber content,the total energy per unit mass and its energy density increase with the increase of the Ti fiber content.With the increase of the distance between the sensor and explosive,the rate of the Ti fiber explosive's peak pressure decay is slower than that of RDX,while the tendency of the shock wave energy and the bubble energy per unit mass with different contents of the Ti fiber explosive is basically in keeping with the increase of the distance.The chemical reaction process of the Ti fiber explosive was also obtained through the total energy per unit mass.%通过爆炸压力时程曲线分析含钛纤维炸药的压力峰值、水下比冲击波能、比气泡能、质量能量及能量密度变化趋势,通过对所得能量结果分析钛纤维炸药的化学反应过程.结果表明:含钛纤维炸药的压力峰值、比冲击波能随钛纤维含量的提高而降低,比气泡能随钛纤维含量的提高而增大,质量能量及能量密度都随钛纤维含量的提高而增大.随距离的增大,钛纤维炸药压力峰值衰减比RDX的慢,而不同钛纤维含量的钛纤维炸药的比冲击波能、比气泡能在不同距离处随钛纤维含量变化趋势基本一致.根据炸药反应释放的总比能量进行理论分析,得出钛纤维炸药爆炸反应方程式.
