摘要

针对反舰武器战斗部对舰船结构毁伤效应的爆炸破片与冲击波两者具有的相关性，对战斗部壳体在爆轰产物内压作用下的膨胀过程进行分析，并结合壳体形成破片的应力准则推导出与壳体材料强度及装药特性参数相关的破片速度计算公式；通过对壳体内装药径向膨胀过程的动量分析获得与装药尺寸有关的等效裸装药计算表达式；结合圆柱形战斗部爆炸实验给出计算算例。

Abstract

The damage effect of warhead of anti-ship weapon on war-ship structure mainly includes the explosion fragments and shock wave, and these two aspects has certain correlation. In this paper, the expansion process of warhead under the inner pressure of detonation products is investigated. The velocity formula of fragments related to the strength of case material and characteristic parameters of charge is derived combing the stress criterion that the case forms fragments. On these bases, the expression of equivalent net charge related the size of charge is obtained through the investigation of moment during the radial expansion process of the charge. Finally, a calculation example is given combing the explosion experiment of cylindrical warhead.
