摘　　要：采用刚性模块柔性连接器(RMFC)模型,柔性连接器假定为线性弹簧模型。基于三维势流理论计算浮体水动力,从而得到连接器的动力响应。计算并比较了3种不同模型在7级海况作用下的连接器动力响应,研究了浅水效应对连接器动力特性的影响,得到超大型浮体连接器动力响应一定的规律,从而为浅吃水超大型浮体连接器的设计提供一定的参考。The rigid module flexible connector model is applied, the flexible connectors are modeled as linear springs. Three-dimensional potential flow theory is adopted to calculate hydrodynamic forces and dynamic response of connectors. The dynamic response of connectors in 3 different models under sea state 7 is analyzed and compared, and the shallow water effect on dynamic characteristics of connectors is studied, which can provide guides for the design of connectors of very large floating structures under shallow draft.
