战斗部对舰船靶标侵彻毁伤效能研究

Study on damage effectiveness of warhead on ship target

针对反舰战斗部侵彻毁伤效能综合评估问题,提出了基于舰船结构特征的等效靶标系统。本文通过推导得到计及攻角的战斗部斜侵彻舰船加筋板架极限速度公式,依据舰船陆地靶标系统设计方案建立了靶标系统数值计算模型。开展反舰战斗部对舰船陆地靶标系统侵彻毁伤效能评估试验,并验证了理论计算结果和数值仿真计算结果。研究表明:舰船陆地靶标系统可对战斗部侵彻剩余速度、姿态角度及弹道偏转和靶标板架毁伤模式进行综合评估,改变了以往以战斗部侵彻钢质均厚板厚度的单一评估模式,为反舰战斗部毁伤评估提供参考。

In this study we propose an equivalent target system that identifies the structural characteristics of the targeted warship to comprehensively evaluate the penetration damage effectiveness of an anti-ship warhead.We deduced a formula for determining the ultimate velocity of a warhead′s oblique penetration into the stiffened plate frame of a ship based on the angle of attack,and also established a numerical model of the target system with respect to the design of the warship land target system.We then evaluated the effectiveness of the anti-warhead penetration damage on the land target system of the warship and verified the results of numerical simulation as well as theoretical formula.The research indicates that the proposed warship land target system can be used to comprehensively evaluate the warhead penetration residual velocity,attitude angle,trajectory deflection,and target plate damage mode,and this changes the existing single evaluation mode of warhead penetrated steel plate based on its thickness and provides a reference for subsequent anti-ship warhead damage assessment.
