摘要

运用有限元仿真方法

探讨了在大装药量武器空中爆炸作用下舰船结构毁伤特性

推导并验证了舰船安全半径。仿真结果表明:在大装药量武器空爆冲击载荷作用下

由于超压作用

舰船水线面以上结构出现大面积塑性变形破坏

并且

响应对爆距变化敏感

而水线面以下结构加速度、应力响应相对较小

且对爆距变化不敏感。在此基础上

总结并验证了大装药量武器空爆作用下的舰船安全半径公式

从而可对舰船状态进行快速评估。研究结果对舰船结构抗毁伤设计具有参考意义。

Abstract

Using the finite element method

the damage characteristic of vessel structure subjected to shock loading induced by air explosion of weapon with massive charge is analyzed.The safety radius of this vessel is deduced and validated as well.The numerical experimental results indicate that the damage resulting from air explosion concentrates on the structure above water plane as the form of extended plastic deformation induced by hyperpressure

and the response is sensitive to detonation distance.While the response

such as stress and acceleration of structure under water plane is weaker

which is insensitive to detonation distance.Based on the research

the safety radius is concluded and validated in order to assess vessel condition quickly.
