摘要:
为了研究JO-6炸药柱的耐热性能,利用自行研制的热爆炸试验系统进行了JO-6炸药柱的全历程试验和180℃条件下的热终止试验。探讨了装药状态对JO-6炸药热爆炸反应温度的影响,分析了有约束和无约束两种条件下HMX转晶对JO-6炸药柱结构和尺寸的影响。结果表明,粉态装药的热爆炸反应温度高于柱态装药,但对晶型转变温度没有明显影响,随着加热温度的升高,两种装药状态下的JO-6炸药均在180℃会发生HMX的转晶吸热,同时引起试样整体结构的破坏,使得试样尺寸增大,密度减小,试样在无约束条件下的结构破坏要大于有约束条件。
Abstract:
In order to investigate the heat-resistance properties of JO-6 explosive, a temperature ramp test and an isothermal test at 180℃ were carried out using the selfconstructed thermal explosion test system. The influence of the charge state on the thermal explosion temperature of JO-6 explosive was discussed and the influence of polymorphic transformation of HMX in both confined and unconfined conditions on its structure and dimension were analyzed. The results show that the thermal explosion temperature of powdery explosive is higher than that of cylindrical charge, while the charge state has no influence on polymorphic transformation temperature. With the temperature increasing, the occurrence of decalescence at 180℃ during the polymorphic transformation of HMX in JO-6 explosive, despite the two charge states, leads to the destruction of the sample, resulting in increasing in dimension and decreasing in density. The sample destruction of unconfined was more serious than that of confined condition.
