台风-浪-流耦合作用超大浮体水弹性响应分析方法
An analysis method for hydroelastic response of very large floating structures under typhoon-wave-current coupling effects
摘要
Abstract
Accurate prediction of the dynamic response of a very large floating structure(VLFS)at a marine airport during extreme marine conditions,such as typhoons,is essential for ensuring safety performance.The challenge lies in accurately constructing a fluid-structure coupling calculation model for the medium/small-scale complex flow field and the floating structure.This paper presents a hydroelastic response analysis method for VLFS at a marine airport based on medium/small-scale nesting.The method begins by implementing a typhoon-wave-current coupling simulation through secondary development and analyzing the space-time evolution of typhoon-wave-current interac-tions on the VLFS as super typhoon Meranti passed over the marine airport.By integrating these calculations into the structural dynamics equation,a bidirectional iterative decoupling solution is obtained.Ultimately,numerical examples are used to analyze the hydroelastic response and the influence mechanism of the floating structure under typhoon-wave-current coupling conditions.The results show that the proposed method can effectively predict the hydroelastic response of a VLFS in such extreme environments.关键词
