两类RMFC模型的对比研究

A Comparative Study of Two Types of RMFC Models

目前使用的RMFC模型有两类。一类是取各模块各自的6自由度运动为基本模态,并在运动方程中加入连接器的刚度。另一类是将超大型浮体的各模块和连接器看作为一个整体,计算其固有模态。论文对这两类模型的理论进行介绍,并对应用这两类模型计算得到的连接器载荷进行对比和讨论。

here are two types of RMFC models with some difference in treatment of connector stiffness.In one of the models,connector stiffness is taken into account in the stiffness matrix in the motion equation,while in another model,connector stiffness is taken into account in the eigenvector in dry mode.Basic theory of these two models was briefly introduced,followed by a comparative study of these two models with a focus on connector loads on large floating structures.
