| 摘 要： | 移动海上基地属于超大型浮式结构物,在营运过程中会遇到飞机坠落,船舶碰撞等事故情况。事故载荷不仅会对超大型浮式结构物的局部结构产生破坏作用,而且会对超大型浮式结构物的薄弱环节——连接器产生附加载荷。以船舶碰撞为例,采用简化的RMFC模型,然后通过SESAM软件计算水动力系数,将其代入多刚体运动微分方程后用数值方法求解,研究特殊载荷对连接器载荷的影响。考虑不同连接器刚度以及不同撞击部位工况,估算碰撞引起的连接器载荷的数量级,并与波浪载荷引起的连接器载荷进行了比较。这为今后移动海上基地连接器设计提供了指导和依据。

| Abstract: | Mobile Offshore Base(MOB) is a kind of Very Large Float Structure(VLFS).It may meet with accidental damage due to airplane collision,ship collision,etc.Accidental loads will not only damage local structures of VLFS,but also induce additional loads on connector which is the weakest part of VLFS.The ship collision is taken as an example,and its influence on the connector is considered.By the use of simplified RMFC model,hydrodynamic coefficient is calculated by SESAM software.Then the hydrodynamic coefficient... |
