摘　　要：由于硝胺炸药本身具有较高的机械感度和冲击波感度,因此现代高能推进剂的安全性受到关注,为了对其安全性进行评估,有必要研究计算NEPE高能推进剂的TNT当量。该文选取由实际爆炸输出来确定爆炸物TNT当量的方法来进行NEPE高能推进剂TNT当量的计算研究。通过10kgTNT炸药和NEPE高能推进剂空中爆炸实验,运用最小二乘原理,利用曲线拟合法,得到了与实验结果吻合较好的TNT炸药、NEPE高能推进剂空中爆炸的仿真压力表达式。求出了压力在0.006MPa^0.500 MPa时,NEPE高能推进剂的TNT当量与对比距离的关系。根据仿真结果,在0.006MPa^0.500 MPa压力范围内,NEPE高能推进剂的TNT当量为1.26。Because the nitramine explosive has high mechanical sensitivity and shock wave sensitivity, the attention is given to the security of modern high energy propellant. In order to evaluate the security of NEPE high energy propellant, it＇s necessary to study and calculate the TNT equivalence of high energy propellant. The method for confirming TNT equivalence from the output of praetieeal explosion is chosen to study TNT equivalence of high energy propellant in this text. The simulation pressure - scaled distance relations consistent with the experiment results got from 10 kg TNT and NEPE high energy propellant explosion are obtained by the least squares algorithm and curve regression. The relationship of TNT equivalence and contrast distance is obtained under 0.006MPa - 0.500 MPa. Based on the simulation results, the TNT equivalence of the NEPE high energy propellant under 0.006MPa - 0. 500 MPa is derived as about 1.26.
