摘要
为了了解切缝药包聚能效应的机理,用动态光弹性法对切缝药包的聚能效应进行了试验,获得了切缝药包爆炸过程中的序列等差条纹图。通过对条纹图的分析,得到了动态应力集中系数,并回归得到了炮孔切缝处剪应力变化的曲线和公式,基本达到了试验的目的。
The experiment was conducted for cumulative effectiveness of slit charge based on dynamic photoelasticity method, and the isochromatic fringes graphs in the process of blasting of slit charge were obtained. By analyzing these graphs, the mechanism of cumulative effectiveness of slit charge was investigated, and the dynamic stress concentration factor and the shear stress attenuation curve of the slot on blasthole were also obtained.
