摘要: 采用楔形装药,用临界截面厚度来表征爆轰波传播特性,分别对两种密度条件下HMX粒度对其自身和以HMX为主体的混合炸药HMX/F2641(wHMX/wF2641=95∶5)爆轰波传播性能的影响作了实验研究。结果表明:HMX粒度对爆轰波传播特性有显著的影响,随着HMX粒度的减小,临界截面厚度变小,即爆轰波传播性能增强;同一HMX粒度下, HMX/F2641爆轰波传播性能优于HMX;装药密度的增加有利于爆轰波传递。Abstract: By adopting wedge-shaped charge and using critical thickness to characterize detonation waves propagation, a experimental study was carried out to explore influences of particle size of HMX on detonation waves propagation of HMX and HMX/F2641 at the two different densities of HMX. Experimental results show as follows: (1) Decrease in size of HMX particle results in diminution of critical thickness, namely enhancement of detonation wave propagation capability; (2) HMX/F2641excels HMX in detonation wave propagation capability at the same size of HMX particle; (3) Increase of charge density is advantageous to detonation waves propagation.
