Analysis of module scale effect on connectors loads characteristics of multi-floating structure
Connectors are crucial and the most vulnerable component of modular multi-floating structure.,Based on the requirements of scale selection and connector safety and stability of modular multi-floating structure,considering both multi-body hydrodynamic coupling effect and mechanical coupling effect of connectors,a coupled time-domain analysis model of a representative three-module floating structure system is constructed based on the three-dimensional nonlinear potential flow theory.The module scale effect on the dynamic characteristic of connectors has been focused and investigated under typical sea conditions.The results show that there is an approximate linear relationship between the increase of module con-nector load and the change of module scale under the same draft,which is the ratio of the displacement of the corresponding scale module.the surge of the large-scale and small-draft module and the longitudinal force on the connector are better.Con-sidering the current construction capacity of the dock and the actual hydrodynamic response characteristics of various scale modules,it is suggested to choose a large-scale module(such as 40 m×40 m)as much as possible,which can provide refer-ence for the structural optimization design of the modular multi-floating structure.
