摘要
以Halbach磁阵多浮体海波发电结构为对象,研究了其在垂荡运动下的能量转换特性。基于线性波理论,建立了线圈浮筒的运动方程和能量转换模型,数值模拟了结构阻尼系数、弹簧刚度系数以及线圈浮筒的长度和半径,此外,数值还模拟了吃水对海波发电结构平均能量转换功率及共振频率的影响。结果表明:根据不同的海波状况,合理设计了海波发电结构的参数,将有助于其平均能量转换功率的提高。
The Halbach permanent magnetic array multiple floating bodies ocean wave generator is studied to explore the energy conversion characteristics under heave motion.The motion equation and the energy conversion model of the coil pontoon are established based on the linear wave theory.The influences of the structural damping coefficient,the spring stiffness coefficient,and the length,radius,draft of the coil pontoon on the average energy conversion power and the resonance frequency of the ocean wave generator are simulated.The results show that the rational structure parameters of the ocean wave generator will contribute to the improvement of its average energy conversion power based on different ocean wave conditions.
