船舶搁浅对船舷外部结构损伤的数值计算研究

Numerical study on damage of ship grounding to external structure of ship's side

船舶搁浅事故是一种全球范围内频繁发生的海上事故,搁浅过程礁石等障碍物会对船体外部结构产生巨大的冲击作用,一旦船体外部结构失效会造成船体破裂等严重事故。本文针对船舶搁浅的场景对船舷外部结构的损伤进行了数值计算和模拟,介绍了结构损伤计算的基础理论。

Ship grounding accident is a kind of maritime accident that occurs frequently in the world.Obstacles such as reefs will have a huge impact on the external structure of the ship hull during the grounding process.Once the external structure of the ship hull fails,it will cause serious accidents such as ship hull fracture.In this paper,the damage of the external structure of the ship's side is calculated and simulated according to the scene of ship grounding,and the basic theory of structural damage calculation is introduced.
