| 摘 要： | 采用不同升温速率3,5,10,25,105℃.min-1分别对PBX-2炸药进行了烤燃试验,试验中用热电偶分别测试样品半径处和中心处的温度变化过程,通过冲击波超压测量分析了样品的反应程度,根据热分析和烤燃试验结果宏观上分析了PBX-2炸药在热作用下的响应规律。试验结果初步表明:热作用试验中PBX-2炸药随着升温速率升高反应程度降低。采用Arrhenius模型对PBX-2炸药在热作用下响应进行了数值模拟,模拟的炸药温度变化结果与试验测试结果基本一致。

| Abstract: | Cook-off tests with different heating rate were carried out for PBX-2 explosive. Temperature changing processes of different positions in the samples were measured by thermocouples, and the reaction degree of PBX-2 explosive was gained by blast pressure gauges. Reaction law for PBX-2 explosive was analyzed macroscopically under heat effect. The results of the tests initially show that the reaction degree for PBX-2 explosive is reduced with higher heating rate in cook-off test. Numerical simulation was made for PBX-2 explosive by Arrhenius model. Calculated temperature result was accord with test result. |
