移动式海上基地多模块间相互作用对连接器载荷的影响

移动式海上基地(MOB)一般由多个模块构成，模块间的相互作用对连接器载荷可能有影响，但在许多现有文献中通常被忽略。计算了考虑模块间相互作用的5模块MOB的模块运动和连接器载荷响应，并与不考虑模块间相互作用的结果进行了比较。结果表明模块间相互作用对不同连接器刚度的MOB连接器载荷的影响不同，在浪向角较小尤其在迎浪时十分明显且不可忽略；当浪向角较大尤其是横浪时，模块间相互作用力较小。

Effect of the multiple modules interaction on MOB connector loads

A Mobile Offshore Base(MOB) is a multi-purpose logistics base which can be stationed in coastal or international waters. Because MOB is connected by many connectors, the interaction forces between multiple modules would have effects on the connector loads. However, the effects of interaction forces are neglected in many literatures. In this paper, the responses of the motions and connector loads of a MOB consisting of 5 modules are calculated, in which the effects of multiple modules interaction are considered. These responses are compared with those without multiple modules interaction. The results show that the effects of interaction on the connector loads are different with different connector stiffness. When the wave angle is smaller, especially in head sea, the interaction forces are larger and can not be neglected. And when the wave angle is larger, especially in beam sea, the interaction forces are smaller.
