摘　　要：针对射孔弹研制过程中,钢靶穿深显著提高而混凝土靶穿深未能同向提高的现象,测试了药型罩轴向密实度的分布,并利用脉冲X光照相观测了射孔弹起爆后的射流形态,分析了药型罩轴向密实度分布不均匀对射流的影响。通过优化前后的射孔弹性能对比试验可知:距药型罩口部约2/5的部分密实度偏低,易造成尾部射流的过早断裂,将降低射孔弹在混凝土靶中的穿深。药型罩轴向密实度分布的均匀性提高5.3%,射孔弹在钢靶中的穿深未受影响,但混凝土靶穿孔深度提高约20.5%。According to the phenomena appearing in the research of shaped charge that its penetration on steel targets was improved obviously,but failed on cement targets,the axial compactness distribution of liner was tested and impulse Xray images of jet form were observed. The influence of uneven axial distribution of liner impact on metal jet was also analyzed. The performance of the optimized shaped charge was compared with the original one,and the results show that compactness of the 2 /5 part nearby the bottom of liner is relatively low that readily causes early fracture of tail jet and accordingly reduces the penetration on cement target of shaped charge. If the uniformity of the axial compactness distribution raise 5. 3%,penetration on steel target would not be influenced,but the depth of penetration on cement target would be increased 20. 5%.
