三峡库区双壳油船碰撞仿真与研究

Collision Simulation and Research of Double-hull Oil Ship of the Three Gorges Reservoir Area

以一艘三峡库区双壳油船为研究对象,通过有限元直接计算,得到被撞船舷侧能量-撞深和撞击力-撞深关系曲线,讨论了不同撞击船初速度和质量、不同撞击点对被撞船舷侧结构碰撞性能的影响,取得了舷侧结构碰撞性能的一般性结论。

The FE analysis was carried out for a double-hull oil tanker of the Three Gorges reservoir area, aiming at the curve of relative between energy and penetration, collision force and penetration. The authors discussed the influence of different mass, initial velocity and collision position to the characteristics of ship side structure in collision, and got the general conclusion of the anti-collision performance of ship side structure in collision.
