摘　　要：对HMX/TATB系列配方和PBX 1的10mm× 10mm、2 0mm× 2 0mm、30mm× 30mm炸药柱进行了非限定热爆炸实验 ,探讨HMX/TATB含量和几何尺寸对热爆炸临界温度的影响。结果表明 :TATB含量增加 ,炸药配方的热感度降低 ,炸药柱热爆炸临界温度增加 ,其增加趋势随TATB含量的增加而变得更加明显 ;炸药柱几何尺寸越小 ,影响越明显 ;线性拟合得到非限定炸药柱热爆炸临界参数δ,药柱半径r和热爆炸临界温度Tm 之间的关系式以及热爆炸延滞期t与临界温度Tm的关系式 ;计算获得PBX 1炸药柱非限定试验In this paper,the unlimited thermal explosion experiments of the HMX/TATB series PBX 1 explosive cylinder are presented.The sizes of the cylinders are 10mm×10mm,20mm×20mm and 30mm×30mm.The influence of the content of TATB and the size of the explosive cylinder on the thermal explosion critical temperature is discussed.The results show that the thermal sensitivity decrease while the thermal explosion critical temperature increase with the increasing of the content of TATB,further more,the smaller the size of the cylinder,the more obvious the phenomena is.By linear simulation the equations that describe the relation of the thermal explosive critical parameter δ ,the cylinder radius r and the thermal explosion critical temperature T m ,as well as the relation between the thermal explosion delay time t and the critical temperature T m are derived.The calculated characteristic critical temperature to keep the PBX 1 cylinder does not to explode for 4 hours during the experiment is obstained too.
