摘　　要：海洋发电轮机所处海上作业环境恶劣,设备易发生故障且维修困难。基于三维势流理论,结合ANSYS-AQWA软件,对风、浪、流荷载联合作用下海洋能发电轮机的水动力特性进行研究,得出发电轮机在工作工况和极限工况下的运动响应特性。结果表明,2种工况下的浮体运动响应幅值的最大值分别出现在遭遇艏斜浪和横浪时;极限工况下的运动响应幅值是工作工况下的3~10倍。该装置经过循环改型之后水动力性能良好,能满足实际的工程应用需求;提出的计算方法可作为一种快速预报装置水动力特性校核手段,满足工程设计阶段的需求。The offshore operating environment where marine power turbines are located is harsh,equipment is prone to failure and maintenance is difficult.Based on the three-dimensional potential flow theory and the ANSYS-AQWA software,the hydrodynamic characteristics of marine energy generating turbines under the combined action of wind,wave and current loads are studied.Motion response characteristics of the power generating turbines under working conditions and extreme working conditions are obtained.The results show that the maximum value of the amplitude of the motion response of the floating body occurs when encountering the oblique wave and the transverse wave respectively;the amplitude of the motion response under the extreme conditions is 3~10 times that under the working conditions.The device has good hydrodynamic performance after cyclic modification,which can meet the practical engineering application.The calculation method proposed in this paper can be used as a check method for quickly predicting the hydrodynamic characteristics of the device,and meets the needs of the engineering design stage.
