摘　　要：为预测半穿甲反舰导弹战斗部穿透船体防护结构外板进入内部爆炸的位置,以进一步对防护结构进行优化设计.根据尖头反舰导弹战斗部动能穿透薄靶板过程的特点,提出了一种简单有效的薄板花瓣型破坏模型,并根据能量守恒原理推导了靶板吸能、弹道极限以及弹体剩余速度公式.由于考虑了靶板材料应变率效应,使得计算结果比现有的花瓣穿甲公式更合理,与实验数据更吻合.It is very important for the naval architect to estimate the explosion location of the semi-armor-piercing missile warhead when designing a warship. A simple and efficient thin plate petalling model was developed based on the characteristic of the kinetic armor-piercing effect of semi-armor-piercing missile warhead. The analysis was executed by means of an energy balance for a rigid-plastic strain rate sensitive material. An excellent correlation was found between the theoretical prediction for the terminal velocity of a projectile striking the target plate and the test results.
