半潜式超大型浮体的多刚体试验研究

超大型浮体作为人类开发海洋的前沿基地,正在成为世界各国海洋工程界研究的一个热点.由于超大型浮体尺度巨大,因此它必定会采用模块化结构,由几种基本的模块在海上加以拼装,连接而成.因此,采用何种形式的连接器已成为超大型海洋浮式结构物设计过程中的一大关键技术问题.本文主要介绍了国内首次进行的半潜式超大型浮体的多刚体试验,在试验中采用刚性模块、柔性连接形式,对各模块的相对运动以及模块与模块之间连接器载荷的动力响应特性进行了研究.

Experimental Research of a Multi-module Semi-submersible VLFS

In exploitation of ocean resources,Very Large Floating Structure(VLFS)has been paid more and more attention.Because of its huge dimensions,in its design and construction,modularized structures must be adopted,and so that a VLFS is typically composed of and interconnected with several basis modules.Consequently,the design of the connector system between the modules has become one of the key technologies in developing VLFS.In this paper,a model test of a 3-module semi-submersible VLFS is presented.In the test,a model composed of rigid modules and flexible connector is used to study the dynamic response characteristics of the semi-submersible modules and connectors.
