摘要

为改善风电整机系统稳定性，提出一种基于亚马逊王莲叶脉分形结构的新型半潜式平台，基于数值模拟研究分形特征对平台水动力学性能的影响。结果表明：仿生平台在降低半潜式平台总质量的同时增加其吃水深度，可有效提升半潜式平台稳定性，纵摇响应改善效果最为显著；当分形维数为1.370时，仿生平台可获得最佳动态响应；随着分形维数的增加，仿生平台腔隙结构尺度不断减小，流体壁面黏性效应增强，形成的不同尺度涡旋相互作用，可有效提高波浪能的吸收效果。

Abstract

To improve the overall stability of wind power systems

a novel semi-submersible platform based on the fractal vein structure of Victoria amazonica leaf was proposed. Numerical simulation was conducted to investigate the impact of fractal characteristics on hydrodynamic performance of the platform. Results show that the bionic platform reduces the overall mass of the semi-submersible platform while increasing its draft

thereby effectively enhancing platform stability

particularly in pitch motion response. When the fractal dimension reaches 1.370

the bionic platform achieves optimal dynamic response. As the fractal dimension increases

the cavity structure scale of the bionic platform decreases

leading to stronger viscous effect along the fluid boundary. The interaction of vortices across different scales contributes to the improvement of wave energy absorption efficiency.
