撞击船载货对双壳油船碰撞损伤的影响

Effect of Striking Ship with Load on Collision Performance of Double-Hull Oil Tanker

为探究撞击船载货对双壳油船舷侧结构碰撞损伤的影响,以7 000吨级双壳油船为原型,运用非线性有限元软件ANSYS/LS-DYNA建立船舶碰撞数值模型,在此基础上对碰撞过程中产生的碰撞力、结构吸能、撞击速度变化和撞深变化等参数进行对比分析,阐述撞击船载货对双壳油船碰撞损伤的影响。研究结果表明,撞击船载货对双壳油船舷侧损伤具有重要影响。

In order to investigate the effect of striking ship with load on the impact performance of the side structure of double hull oil tanker,a 7 000 ton double hull oil tanker is taken as a model,and the ship collision numerical model is established by nonlinear finite element software ANSYS/LS DYNA.Based on the comparitive analysis of the collision force,structural energy absorption,striking speed changes and striking deep changes during the collision process,the influence of the striking ship with load on the impact performance and damage mechanism of the double hull oil tanker side structure is expounded.The results show that the influence of the striking ship with load is great to the damage to side hull of the oil tanker during the collision.
