| 摘 要： | 以被撞船舷侧结构作为研究对象,建立了两船发生侧向对中垂直碰撞的非线性有限元模型。并以此为基础,进行了被撞船舷侧结构碰撞数值仿真研究,得到了能量-碰撞船位移以及碰撞力-碰撞船位移的关系曲线;研究了预载荷对船舶舷侧结构碰撞性能的影响。数值仿真结果表明,由于船体梁载荷的作用,船舶结构碰撞性能受到一定程度的削弱。

| Abstract: | To study the ship collision performance of the side structure under preload through numerical simulation,a non-linear finite element model of the ship-ship side collision is built.The time histories of collision force,energy absorption and structural deformation during collision are obtained.The study of influence of the preload on the ship collision performance is the main purpose.The results of the simulation considering preload are compared with the scenario without considering preload.It is indicated that the ship collision performance is weakened under preload. |
