Experimental Investigation of Ignition Features for Solid Explosive Charges under Pressure-Shear Loading

摘要: 采用平面正碰撞Y-切面石英,使之产生压剪波传入粘接在石英后表面的炸药(T/Г40/60,10#-159)试件中的方法,实现对炸药试件的一维平面压剪复合加载。用埋入多重拉格朗日量计──电磁质速计,记录传入炸药试件中的纵向运动和横向运动变化历史,分析炸药中压剪波的传播规律,从而认识炸药在压剪加载下的起爆响应特点。Abstract: In this paper, one-dimensional planar pressure-shear loading upon solid explosive charges (T/Г40/60, 10#-159), which were cohered to the rear surface of the quartz piece, were realized by means of the waves propagation resulting from planar impacting on a Y-cut quartz piece. Longitudinal (or normal) and transverse (or shear) movement histories in the explosive samples were recorded by means of electric-magnetic particles velocity (EMPV) gages. They are Lagrangian gages embedded in the sample. By analysis of the law of pressure shear wave propagation in the sample, which would result in the realization of ignition features of solid explosives under pressure-shear loading.
