摘　　要：采用基于升力面自由尾迹的气动预测方法构建浮式风力机全耦合模型,采用多体系统动力学模型描述浮式风力机系统的运动响应,基于准静态假设计算系泊系统的系泊力,基于改进Morison公式计算水动力。结果表明:采用全耦合模型计算得到的叶尖涡轨迹预测值与实验值吻合良好;基于全耦合模型预测得到的浮式风力机运动轨迹与FAST计算结果吻合良好;在风波联合作用下可观察到较为明显的气动-水动耦合现象。A full coupling model of the floating wind turbine was constructed by aerodynamic prediction method based on lifting surface free wake,motion response of the floating wind turbine system was described by multi-body dynamics.Moreover,mooring load of the mooring system was calculated based on the quasi-static assumption,and the hydrodynamic load was calculated based on the improved Morison formula.Results show that predicted values of the blade tip vortex trajectory calculated by the fully coupled model is in good agreement with experimental results.The predicted trajectory of the floating wind turbine based on the fully coupled model is in good agreement with the FAST calculation results.The phenomenon of aero-hydrodynamic coupling can be observed obviously under the combined action of wind and wave.
