摘要:
为研究炸药药柱在低速撞击复合刺激下的安全性，建立了炸药药柱低速撞击复合环境试验系统，对－40、20、70℃的B炸药与JO8炸药柱进行了低速撞击感度试验。采用气敏检测系统监测药柱撞击密闭腔室内CO、CO2以及H2 3种气体的浓度来判断药柱的爆炸状况，提高了试验结果判断的准确性，获得了不同温度下B炸药与JO8炸药柱的临界落高。结果表明，温度与炸药药柱临界撞击高度并没有很直接的关系，B炸药与JO8炸药的药柱撞击安全性在一定温度范围内（20~70℃）对温度不敏感，低温环境下B炸药稍有钝感，而JO8炸药则趋于更加敏感。
Abstract:
In order to study the safety of explosive columns under low speed impacting multiple stimulations, the multiple environments test system was established and the lowimpact sensitivity tests of Composite B and JO8 were carried out under the temperature of －40 ℃, 20 ℃and 70 ℃. The density of CO, CO2and H2 in the impacting hermetic room were monitored by the gassensitive detection system to determine the status of the columns explosion, which improves the accuracy of the judgment of explosion. The critical drop height of Composite B and JO8 under three different temperatures was obtained. The results show that the critical drop height has no very direct relationship with temperature. The impacting safety of Composite B and JO8 is not sensitive to temperature in a certain temperature range from 20 ℃to 70 ℃. Under an environment with lower temperature, the Composite B is slightly insensitive and JO8 tends to be more sensitive.
