    以DTU 10 MW基准风机为研究对象,单柱式平台作为基础支撑结构,使用FAST软件计算分析,考虑单独风、单独波浪以及风浪组合三种环境条件,对10 MW级海上浮式风机的运动特性进行研究。研究发现:系统摇荡是风激励的低频运动和波浪激励的波频运动的合成,气动阻尼削弱系统的波频运动;系统纵荡和纵摇运动存在明显的耦合现象,而垂荡运动和其他方向的运动没有耦合关系;受纵摇影响,转动的风轮产生陀螺惯性力矩,激励首摇运动;随着风机单机容量的增加,风激励的低频运动比例增大,波浪激励的波频运动比例减小。Taking the DTU 10 MW reference fan as the research object, the single column platform as the foundation support structure, using the FAST software calculation and analysis, consider

Single wind, wave and wave combination, the motion characteristics of 10 MW marine floating fan are studied. research

It is found that the system sway is the synthesis of the low frequency motion and the wave excitation of the wave excitation. The aerodynamic damping system

There is a clear coupling between the system and the pitching motion, and the movement of the heave and the other directions has no coupling relationship.

Shake the wind rotor to produce the inertia moment of the gyroscope, to stimulate the first shake movement; with the fan capacity increases, the wind excitation of the low-frequency transport

The proportion of the wave is increased and the proportion of the wave excitation is reduced.
