采用刚性模块刚性连接器（RMRC）模型对模块化海上平台连接器的动力特性进行了研究。在该模型中，将由模块拼装而成的海上平台看成一个整体结构，而连接器的载荷简化为结构相应剖面的载荷。基于三维势流理论，通过引入“高频低速”的假设，推导了低航速浮体在波浪中运动及载荷响应分析的理论和方法。计算了2种海况、4种结构尺寸、7种浪向角下结构连接器的载荷响应，得到了连接器动力响应与海况、结构尺寸及浪向角之间的关系和规律，为模块化海上平台连接器的设计及使用提供了有益的借鉴。

A rigid module rigid connector(RMRC) model is used to study the dynamic characteristics of connectors of modular offshore platform. It is assumed that the modular offshore platform is a whole structure and the connector loads are simplied as the corresponding section loads is deduced using the Three-Dimensional Potential Theory by means of the assumption—High Encounter Frequency with Low Sailing Speed. 2 sea state cases, 4 structure sizes, and 7 wave angle connectors are calculated gaining the dynamic responses and sea states of connectors,and the regularity and relationship between configuration sizes and wave angles which is useful to design and utilization of connectors.
