| 摘 要： | 分别采用热爆发延滞期试验和撞击感度试验测定了12种不同RDX和铝粉含量的含铝炸药的5 s爆发点(Tb)和特性落高(H50),并根据实验数据计算出热爆发参数(Eb和lnA)和特性落高能(Edr)。结果表明:随着RDX含量的增加,特性落高先减小后逐渐升高,特性落高能(Edr)与热爆发参数(Tb、Eb和lnA)之间存在线性关联关系。

| Abstract: | The thermal explosion temperature (Tb) was determined by heat explosion test and the drop height (H50) was obtained by impact sensitivity test for 12 types of RDX-based aluminized explosives with different contents of RDX and aluminum powder respectively. The heat explosion parameters decreased to the lowest when RDX content reaches 89%(Tb, heat explosion activation energy(Eb) and logarithm of pre-expontential factor(lnA)), and drop energies (Edr) were calculated with experiment data. The results show that the drop height (H50) first fall down and then rise with the increasing of RDX contents. Additionally, it is found that a linear relationship exists between the drop energies (Edr) and heat explosion parameters (Tb, Eb and lnA). |
