连接器对多模块浮体系统的运动响应有很大影响,但如何合理地在模块的端面上布置连接器目前并没有规律可循。本文提出一种科学的策略,供设计人员确定超大型浮式结构物(VLFS)的最优连接器布局。为此,建立了多浮体系统的网络模型,分析连接器布局对系统响应的影响。为了确定影响优化的最主要因素,采用敏感性分析法对连接器位置与模块和连接器动力学响应之间的关系进行评估。然后,根据不同海况下的具体工程要求设置约束条件,提出一种基于定制化目标的连接器布局优化策略。在对三模块浮体系统的数值研究中,找到不同权重组合下的最优连接器布局方案。该工作可为超大型海上浮式结构物的连接器布局设计提...

Connectors have a great impact on responses of multi-modular floating systems, but there is no rule to obey for how to reasonably arrange the connectors on the module's end face. This paper presents a scientific strategy for determination of the best connector layout for very large floating structures (VLFS). To do so, a network model of VLFS was established for analyzing the effect of connector layouts on the system responses. To identify the most influential factors for optimization, a sensitivity analysis was employed to evaluate the relatio...
