摘要

摘要 圆柱形定型装药是由爆炸材料包围的空心圆柱形衬垫。圆柱形积放的射流形成很难实现,但由于其特点:积放射流的速度高,而且与传统积放相比,射流速度沿长度方向的梯度小,因此引起了研究人员的兴趣。为了实现稳定的射流形成,有人提出了一种两级圆柱形装料装置。其工作原理是在炸药内部装药中建立一个过压缩起爆机制。因此,内壳向轴线抛射的速度会增加,这将导致内壳坍塌角增大并改善射流的形成。本文介绍了这种装置运作的数学模型,并考虑了这种定型装药的几种选择。从数学角度看,这种装置在过压缩起爆状态下运行的可能性已得到证实。

Specificities of Throwing the Shell of a Cylindrical Cumulative Charge to the Axis

Abstract

A cylindrical shaped charge is a hollow cylindrical liner surrounded by explosive material. Jet formation in cylindrical cumulation is difficult to achieve, but is of interest to researchers due to its features: the high speed of the cumulative jet and the low gradient of jet speeds along the length relative to classical cumulation. To achieve stable jet formation, a two-stage cylindrical charge device has been proposed. The principle of its operation is based on the creation of an overcompressed detonation regime in the internal charge of the explosive. Thus, the speed of throwing the inner shell towards the axis will increase, which will lead to an increase in the angle of collapse of the shell and improved jet formation. A mathematical model of the functioning of such a device is presented, and several options for such shaped charges are considered. From a mathematical point of view, the possibility of functioning of such a device in the overcompressed detonation regime has been proven.
