| 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/F2641 excels HMX in detonation wave propagation capability at the same size of HMX particle;(3) Increase of charge density is advantageous to detonation waves propagation. |
