摘要

为探究间距比对半潜式海上风力机涡激运动的影响

采用拖曳水池模型试验的方法

开展45°流向下

间距比对于半潜式风力机涡激运动响应幅值、频率以及运动轨迹等关键特征影响的研究

观察到较为明显的涡激运动的3个阶段：非锁定区、锁定区以及超锁定区

讨论不同阶段中间距比对半潜式风力机横荡、纵荡以及艏摇运动响应幅值的影响

并着重分析各阶段中结构三向运动的耦合关系及运动频率特征。研究表明：间距比是决定半潜式风力机三向运动响应幅值的重要因素

更大的间距比可能导致更为激烈的运动

从而使结构发生疲劳损伤的危害性更大;间距比对结构三向运动耦合关系影响不明显

同时

各间距比结构运动轨迹随约化速度变化规律基本一致。

Abstract

In order to investigate the effect of spacing ratio on the vortex-induced motion of semi-submersible offshore wind turbine

this paper adopts the method of towed pool model test to carry out the research on the effect of spacing ratio on the key features of the response amplitude

frequency and trajectory of the vortex-induced motion of semi-submersible wind turbine at a 45° incidence. Three phases of more pronounced vortex-induced motion were observed

i.e. per-lock-in region

lock-in region

and post-lock-in region. It is shown that the spacing ratio is an important factor in determining the amplitude of the three-way motion response of a semi-submersible wind turbine

and that larger spacing ratios may lead to more intense motions

which may result in a greater risk of fatigue damage to the structure. The effect of spacing ratio on the structure three-way motion coupling relationship is not obvious

at the same time

while the structure motion trajectory of each spacing ratio is basically the same as the rule of change of reduced velocity.
