中文摘要:
      浮式模块间的连接结构对多模块结构在波浪作用下的运动响应和浮体结构系泊系统受力有重要的影响。本文开展了波浪与两模块组成的系泊浮体结构作用的物理模型试验,对比了模块间连接刚度对模块运动响应和系泊力的影响,并考虑了两种浮体系泊刚度。实验中采用拉伸弹簧模拟模块间的连接结构,通过改变连接弹簧的刚度模拟不同的连接结构的刚度。实验结果表明,改变连接刚度可以显著改变结构纵摇运动幅值,但对结构的纵荡和升沉运动影响较小。实验结果可为多模块间的连接设计提供参考依据。
英文摘要:
      The connection structure between floating modules has an important influence on the motion response of the multi-module structure and the mooring system force. In this paper, physical modelling tests of the wave actions on a moored floating body composed of two modules are carried out. The effect of the connection stiffness between the two modules on the module motion response and mooring force are investigated, and two mooring stiffnesses are also considered. Tension springs are used in the experiments to simulate the connection structure between the modules, and the stiffness of different connection structures is simulated by changing the stiffness of the connection springs. The experimental results show that changing the connection stiffness can significantly change the amplitude of the pitch motion of the module, but it has less effect on the surge motion and heave motion structure. The experimental results can provide a reference for the design of the connection between multi-modules.
