摘　　要：为了揭示2,4-二硝基苯甲醚(DNAN)基不敏感熔铸炸药的爆轰特性,加快DNAN基熔铸炸药的应用,采用Fortran BKW代码计算了Octol炸药和不同组分DNAN基熔铸炸药的爆轰参数(爆速、爆压)。采用电测法、爆炸概率法和激光干涉测速技术分别对DNAN基配方DNAN 20/奥克托今80和Octol炸药的爆速、爆压、机械感度以及金属板驱动能力进行了试验测试。试验结果表明:该DNAN基炸药的爆速为8 436 m/s,爆压为31.23 GPa,爆轰性能优于Octol炸药;撞击感度为33%,摩擦感度为57%,机械感度低于Octol炸药;驱动金属板速度达到3 045 m/s,优于Octol炸药。该DNAN基高爆速熔铸炸药综合性能优于Octol炸药,可替代Octol炸药用于防空反导和大口径爆炸成型弹丸战斗部。In order to reveal the detonation properties of 2,4-dinitroanisole（ DNAN）-based melt-cast explosives and promote the application of this kind of explosives,a computer code is used to calculate the detonation properties of three DNAN-based melt-cast explosives. A series of experiments are carried out to characterize the properties of the DNAN-based explosive（ DNAN 20 / HMX 80） and Octol. Electrometric method is used to test the detonation velocities and pressures of the two explosives. Explosive probability method is used to test the mechanical sensitivities of the two explosives. Laser interferometer velocimetry（ VISAR） is used to test the free surface of copper bar drived by the detonation products. The results show that the detonation properties（ detonation velocity is 8 436 m / s and pressure is 31. 23 GPa） of DNAN-based explosive（ DNAN 20 / HMX 80） are better than those of Octol. The mechanical sensitivity of DNAN-based explosive（ impact sensitivity is 33% and friction sensitivity is 57%） is lower than that ofOctol. The speed of the copper bar drived by the detonation products is 3 045 m / s. The comprehensive performance of DNAN-based explosive（ DNAN20 / HMX80） is better than that of Octol. The DNANbased explosive could replace Octol for air defense warhead,antimissile warhead,and large-caliber EFP warhead.
