摘要
在爆炸抛撒颗粒群的应用中,颗粒群的速度控制非常重要。针对此问题,通过对几种不同粒径、形状和材料的颗粒进行试验,得到了爆炸驱动的颗粒群对相同距离上纸靶侵彻深度的分布规律。结果显示,颗粒的尺寸是影响其速度分布的最主要因素。尺寸在0.3mm以下的不规则颗粒对纸靶的侵彻深度呈指数型分布,0.3mm以上的颗粒近似成正态型分布。进一步分析了颗粒着靶速度和颗粒初速的分布与颗粒对纸靶侵彻深度分布间的关系。结果表明,颗粒的着靶速度、初速与侵彻深度间有相同的分布类型。
Velocity control is very important for the application of explosive dispersing particles.Aiming at this problem,the distribution rule of penetrating depth on the paper target of particles dispersed by explosive was experimentally studied for different particle sizes,shapes and materials.The result shows that the size of the particles is the main factor affecting velocity distribution.It is an exponential type when the size of particles is less than 0.3 mm,and it is a normal type when the size of those particles is more than 0.3mm.With the analysis of the relationship of the distributions between the penetrating depth,impact velocity and initial velocity,the impact velocity and initial velocity have the same distribution type with the penetrating depth.
