一种温压炸药的爆热表征与影响因素分析

Explosion heat characterization and influencing factor analysis of a thermobaric explosive

在对温压炸药的能量测量方法进行分析的基础上,以TNT(三硝基甲苯)为例,采用绝热式量热测量仪对温压炸药进行了相关研究,并对温压炸药能量测量时的影响因素进行了分析。结果表明:随温压炸药的氧平衡增大,释放出的能量增加;在相同气氛下,装药密度越大,释放出的能量越多;量热系统的蒸馏水纯度越高,系统越容易达到平衡且系统热容误差越小。

Based on the analysis of the energy determination method of the thermobaric explosive,the related investigations of the thermobaric explosive were carried out using the adiabatic calorimeter,and the influencing factors for determining energy of the thermobaric explosive were analyzed using TNT(trinitrotoluene)as an example.The results show that the released energy increases with the increase of the oxygen balance of the thermobaric explosive;under the same atmosphere,the released energy increases with the increase of charge density;as the purity of the distilled water goes higher in the calorimetric system,the system is easier to reach equilibrium,and the heat capacity error of the system is smaller.
