摘要:
为了研究TNT在密闭空间中的能量释放特性，依据量热法原理测量了TNT炸药在不同环境中（真空、0.1 MPa空气、0.1 MPa氧气）的爆热；同时在自行设计的密闭爆炸仓内，采用PCB压力传感器和K型热电偶分别测量了TNT炸药在不同气氛（空气、氮气、纯氧气）中爆炸后的准静态压力和爆炸场温度。爆热测试试验结果表明，当环境中氧含量增加时，爆热也随之增加；密闭空间中爆炸参数测量结果表明，随着密闭环境中氧含量的增加，准静态压力和爆炸场温度均有所增加。这说明实际应用中TNT爆炸反应完全性较低，有大量能量未释放，密闭条件可以提高TNT爆炸能量释放率。
Abstract:
In order to study the energy release characteristics of TNT in enclosed condition, the detonation heat of TNT in different environments(vacuum, 0.1MPa air or 0.1MPa oxygen) was tested by the calorimetric method. And the quasistatic pressure and explosion temperature of TNT in different air condition (air, N2 and O2) were measured respectively using PCB company piezoelectric pressure sensors and thermocouple of type K. The detonation heat test results show that when the oxygen content of gas condition increases, the detonation heat of TNT also increases. The quasistatic pressure and explosion temperature tests also show that the same results.All of these indicate that in the practical application the completion of the TNT explosive reaction is much low, where there is a lot of energy is unable to be released, but the enclosed condition can improve the ratio of TNT energy released in explosion.
