摘　　要：对HMX、PBX-1及PBX-2三种炸药进行了不同颗粒粒度下的撞击感度试验和摩擦感度试验,结果显示HMX的机械感度随着HMX颗粒度的增加而增加总的趋势;PBX炸药随着颗粒度的提高,摩擦感度略有提高,而撞击感度未发现明显变化。由于粒度不同造成装药密度不同是造成HMX的机械感度颗粒度波动的原因。实验结果可指导确定炸药配方研制中HMX粒度,为制定相应的具体实验工艺提供技术支撑。In order to study the influence of particle granularities of HMX and PBX on impact and friction sensitivities,impact sensitivity and friction sensitivity trials of three explosives including HMX crystal particles,PBX-1 and PBX-2 were carried out under different grain size.Results show that the sensitivities of HMX crystals increase with the increase of the granularity.For PBX explosive particles,with the improvement of grain size,friction sensitivity increased slightly,and there is no trend of the impact sensitivity can be found.Due to that different particle size of powder samples in the same experiment device can form different charge density;this may be the reason that causes mechanical sensitivity of HMX increased with the increase of HMX particle degree.
