摘要

针对抛撒装药能量输出方式决定爆炸驱动能力大小,传统的圆截面抛撒装药结构存在爆轰能量周向输出方式单一等问题,通过改变抛撒装药截面形状控制爆轰能量输出方式,研究了圆形、五角星形和花瓣形3种抛撒装药结构对被抛撒介质的爆炸驱动作用大小,抛撒装药结构的比药量均为2%,研究发现:装药爆炸驱动被抛撒介质的能力由其截面积大小决定,受抛撒装药截面形状的影响很小,分析原因主要是非圆截面抛撒装药爆炸产生的冲击波在传播过程中波阵面能量迅速匀化,无法对被抛撒介质产生定向加载效果;在壳体外壁有刻槽的情况下,主射流结构数量与刻槽数量相同,受抛撒装药结构截面形状影响不大。

Abstract

The energy output mode of the dispersal charge determines its explosive driving capacity to the dissemination medium, while the traditional circular cross-section dispersal charge structure has the problem of a unique circumferential output mode of explosive energy. In this work, the energy output mode is changed by changing the cross-section shape of the dispersal charge. The explosive driving effect of three kinds of dispersal charge structures (circular, star and flower shaped) on the dispersal medium is studied. The fill-to-burster mass ratio of three kinds of dispersal charges is kept at 2%. It is shows that the ability of the charge to drive the dispersal medium through explosive is determined by its cross-sectional area, and is little affected by the cross-section shape of the dispersal charge. The reason is that the energy inhomogeneity of shock wave caused by the non-circular charge structure is rapidly homogenized during its propagation. Additionally, when the shell is engrooved on its external surface, the number of primary jet structures is the same as the number of grooves, and has little relationship with the sectional shape of the charge structure.

Key words： explosive dispersal; non-circular shaped explosive charge; jet; cloud size
