摘　　要：鉴于线性聚能装药在民用和军事领域的广泛用途,本文在顶面中心线同时起爆方式下,将线型聚能装药形成爆炸成型弹丸的三维问题简化为二维问题。给出了楔形药型罩翻转速度的计算公式,并编制算例计算了罩顶和罩底微元的翻转速度,同时结合算例拟合出不同张角下药型罩翻转速度沿母线的分布规律,为线性爆炸成型弹丸的设计提供一定参考。According to the widely use of linear shaped charge in the field of military and civilian, the three-dimensional question of explosively formed projectile using linear shaped charge is simplified to planar question in the way of igniting dynamite from top midline. The calculation formula of the turning speed of wedge shaped liner is put forward, and then the turning speed of shade element is calculated and the distribution regularities of the turning speed of liner along the generatrix under different flare angles is also simulated using examples, which will set up a reference for the design of linear explosively formed projectile.
