对半潜式风机的浮体进行参数化分析，旨在得到浮体不同组成部分的形状参数对风机水动力性能的影响。在保证风机浮体排水量不变的前提下，频域分析结果表明，浮体立柱与浮筒尺寸的改变，对风机的固有周期及幅值响应算子（RAO）的峰值有较大影响；垂荡板的参数化分析结果表明，垂荡板可显著改变风机的固有周期，对各运动RAO幅值的影响与其形状密切相关；时域计算结果表明，在风机浮体上加装垂荡板，可导致风机在极限海况下纵荡和纵摇的平均漂移运动增加，出现较大的极值，但其可显著降低垂荡响应的极值；对于最大作业波浪工况，垂荡板对各运动均值、标准差及极值的影响取决于垂荡板的形状与安装位置。

英文摘要:

This study conducts a parametric analysis of the floater of a semi-submersible wind turbine to investigate the influence of shape parameters of different structural components on its hydrodynamic performance. Under the condition of constant displacement of wind turbine floater, frequency-domain analysis results indicate that variations in the dimensions of the columns and pontoons significantly affect the natural periods of the turbine and the peak values of the response amplitude operator (RAO). The parametric analysis of the heave plate shows that it can substantially alter the natural periods of the turbine, while its influence on the RAO amplitudes of various motions is closely related to the shape of the heave plate. Time-domain simulation results demonstrate that the installation of a heave plate on the wind turbine floater increases the mean drift motion of surge and pitch under extreme sea conditions, leading to larger peak values; however, it significantly reduces the peak heave response. Under maximum operational wave conditions, the influence of the heave plate on the mean, standard deviation, and peak values of different motions depends on its shape and installation position.
