高含铝炸药爆炸过程中的能量分析

摘要

在野外静爆实验中,利用高分辨率、高精度冲击波超压系统分别测试了高含铝炸药和TNT的爆炸场冲击波超压,根据试验数据,计算该含铝炸药的爆炸场冲击波超压的TNT当量,利用TNT当量评价该高含铝炸药的威力,用能量反演方法分析该含铝炸药中可燃组分的反应程度和可能的反应模式,计算可得该含铝炸药爆炸反应释放能量的有效利用率为65.41％,为高含铝炸药配方优化设计提供新的研究方法.%The shock wave overpressures were measured in explosion field tests for high aluminized explosive and TNT with high resolution and precision. Based on the experimental data and explosion law, the TNT equivalence of shock wave overpressure in explosion field for high aluminized explosive was calculated. The power of aluminized explosive was estimated by TNT equivalence, and the energy inversion principle was applied to assess the reaction extent of combustible components and possible reaction patterns of metal component. It is obtained by calculation that the effective utilization of energy in the aluminized explosive is 65. 41% , which provides a new approach for aluminized explosive optimization design.
