摘要

针对半潜式海上漂浮式风力机在极端海况下的大幅摇荡响应，受亚马逊王莲水动力特性启发，提出一种具有叶脉分支结构的新型半潜式平台，以改善漂浮式系统稳定性。通过计算流体动力学方法，结合动态流-体相互作用模型，分析不同分支级数对仿生平台动态响应影响。结果表明，随分支级数增加，仿生结构对平台水动性能改善效果逐渐增强；当叶脉分支级数为8时，仿生平台稳定性最佳，纵摇标准差较原始平台降低30.83%；分支结构内易产生密集的涡旋分布，能有效增强系统能量耗散，其中，8级分支结构的平均旋转较原始平台降低50.97%。研究提出的仿生叶脉结构在提升平台整体稳定性方面具有显著优势。

Abstract

Inspired by the hydrodynamic characteristics of the Victoria Amazonica

a novel semi-submersible platform with a leaf-vein branching structure is proposed to improve the stability of floating offshore wind turbines under extreme sea conditions. Based on computational fluid dynamics combined with a dynamic fluid-body interaction model

the effects of different branch levels on the dynamic responses of the bionic platform are analyzed. The results show that the enhancement of hydrodynamic performance by the bionic structure increases with the branch level; the platform exhibits optimal stability at a branch level of 8

with the pitch standard deviation reduced by 30.83% compared with the original platform. Dense vortex formation within the branching structure effectively enhances system energy dissipation

with the mean rotational energy of the 8-level branching structure decreased by 50.97% relative to the original platform. The bionic leaf-vein structure proposed in this study offers a significant improvement in the overall stability of the platform.
