摘要

旨在研究风载方向和波浪方向不共线对浮式风机基础动态特性影响。以5 MW浮式风机为研究对象，采用等效载荷法模拟空气动力载荷，建立浮式风机系统耦合动力学模型，研究风浪呈0°、30°、60°和90°夹角工况时，浮式风机基础动态特性变化。结果表明：风浪不共线对浮式平台纵荡和横荡运动平衡位置影响很大，对垂荡运动响应影响很小。随着风浪夹角增大，横摇和艏摇运动振荡范围增大，纵摇运动振荡范围减小。风浪不共线使得系泊系统张力响应变化明显，张力变化趋势与平台运动及系泊布置有关。

Abstract

Here, effects of wind-wave misalignment on dynamic characteristics of a floating offshore wind turbine foundation were investigated. A 5 MW floating offshore wind turbine was taken as the studying object, its aerodynamic loads were simulated with the equivalent load method, and its coupled dynamic model was established. Under working conditions of wind-wave angles of 0°, 30°, 60° and 90°, changes of dynamic characteristics of the turbine foundation were studied. Results showed that effects of wind-wave misalignment on the floating platform’s surge and sway equilibrium positions are very large, while wind-wave misalignment has little effects on the floating platform’s heave response; with increase in wind-wave angle, the platform’s roll and yaw oscillation ranges increase, while its pitch oscillation range decreases; wind-wave misalignment makes the mooring system’s tension response vary obviously, the tension variation trend is related to platform motions and mooring arrangement.
