对 HMX颗粒炸药和 JOB- 90 0 3炸药进行了燃烧转爆轰 (DDT)实验 ,研究了炸药组分、装药密度以及约束条件对 DDT过程的影响 ,分析了炸药 DDT的机理 ,实验结果表明炸药 DDT过程和炸药组分以及装药状态有很大关系 ,HMX颗粒炸药容易发生 DDT现象 ,而以 HMX为主要成分的 JOB- 90 0 3压装装药不容易发生 DDT现象。
The combustion detonation-detonation (DDT) experiments of HMX and JOB-90 0 3 explosives were carried out. The effects of explosive composition, charge density and restraining conditions on DDT process were studied. The mechanism of DDT was analyzed. The experimental results show that The DDT process of explosives is closely related to the explosive components and the state of charge. The DDT phenomenon is easy to occur for the HMX particle explosives, while the DDT phenomenon is not easy to occur for the JOB-9030 press charge with HMX as the main component.
