| 摘 要： | 针对船舶与海洋平台碰撞问题,研究船舶不同碰撞位置对平台结构损伤的影响。基于非线性有限元方法对船舶与海洋平台碰撞的场景进行数值模拟。对船首、船中和船尾碰撞这3种情况下的平台损伤特性进行比较分析。结果表明,这3种情况下的碰撞时间、碰撞力和碰撞位移以及平台局部损伤、整体变形和总吸能等存在着较大的不同,平台具有不同的损伤特征。

| Abstract: | Aiming at the collision problem between ships and offshore platforms, the influence of different collision parts of ships on the damage of platform structure is studied. The scenes of collision between ships and offshore platforms are numerically simulated by the nonlinear finite element method. The damage characteristics of platforms under three conditions of bow, mid ship and stern collision are analyzed. The results show that there exists big difference in the collision time, the collision force, the collision displacement, as well as the local damage, the overall deformation, the total energy absorption of platforms under the three conditions, and the platforms are of different damage characteristics. |
