本文基于三维势流理论，利用AQWA软件对四月池驳船式浮式风机进行了风浪联合海况的性能分析。首先，测得频域内浮式风机的附加质量、辐射阻尼和一阶波浪力水动力系数，分析水动力系数随入射波频率变化。其次，监测了时域内四月池浮式风机在波浪环境和不同风速条件下风浪联合环境下的运动响应，比较了不同风速对运动响应的影响程度。结果表明，整体的纵摇角度对风速的大小非常敏感，而垂荡幅值随风速变化不明显。同时对比不同月池结构的纵摇角度，在低风速条件下四月池结构具有较好的稳定性。
Based on potential flow, using AQWA study motion characteristics of barge-type floating wind turbine (FOWT) with four moonpools under wave and wind. Firstly，the important hydrodynamic coefficients of FOWT, such as added mass、radiation damping and first-order wave force, are investigated in frequency domain, and then the relationship between hydrodynamic coefficients and incident wave frequency is analyzed. Secondly，the motion response of FOWT under wave and different speed of wind are monitored，and the influences are compared with different wind conditions. The results show that pitch amplitude is very sensitive by wind speed，however heave motion is contrary to pitch。And then compared with the pitch of different moonpool structures, the four moonpool structures have better stability under low wind speed.
