摘要
采用自行设计的快速烤燃试验方法,测试厚度为2,4,6 mm梯恩梯（TNT）装药壳体的响应状态,结合TNT的高压差示扫描量热（PDSC）分解特性,研究了厚度对炸药装药响应的影响。结果表明：在快速烤燃试验条件下,壳体厚度由2~6 mm变化时,TNT炸药均为爆炸反应等级;壳体厚度变化对TNT炸药响应等级没有显著影响,但炸药装药反应对外做功能力提高;PDSC结果显示,随着环境压力的提高,反应释放热量增大,TNT分解量增大。
Using a self-designing fast cook-off set-up,the response of 2,4,6-trinitrotoluene（TNT）explosive with the thickness of 2,4,6 mm confinement were tested,and the influence of thickness on the TNT explosive cook-off characteristics were studied using the pressure differential scanning calorimetry（PDSC）teconology.Results show explosives exploded with different confinement.With the pressure increasing the decomposition temperature of TNT increased,which shows its reaction rate and energy release increased.Therefore,PDSC could be used for inspecting the explosive cook-off response.
