为确保海洋浮标能够获得稳定且持续的电力供应,提出一种双体波浪能转换装置,其核心结构由两部分组成：一部分是可根据需要调节质心位置的摆体,另一部分是用于漂浮的浮标。依据该装置的设计参数构建相应模型。随后,借助AQWA软件对装置模型进行网格划分操作。在此基础上,对AQWA软件中的频域模型进行网格无关性验证。最终,分别针对单体和双体结构开展频域仿真研究,并对比分析新型双体波浪能发电装置的频域特性。结果表明：摆体的俘能效果在波浪频率为0.2 Hz时最好,而浮标的稳定性在波浪频率为0.33 Hz时最强;双体的水动力参数在某些频率范围内与单体的对应参数有所差别,结合海洋浮标和摆体的新型波浪能发电装置在波浪频率小于0.18 Hz时的俘能效果较强。
Abstract
In order to supply stable and continuous power to ocean buoys,a new two-body wave energy conversion device is proposed. The main body of the device is composed of a buoy and a pendulum with adjustable center of mass position. The model is established according to the design parameters of the new two-body WEC. The device model is meshed using AQWA software. The grid independence test is carried out on the frequency domain model of AQWA. Finally, the frequency domain simulations of the single body and the double body are carried out, respectively. The frequency domain characteristics of the new double-body wave power generation device are compared and studied. The results show that the energy harvesting effect of the pendulum is the best when the wave frequency is 0.2 Hz, and the stability of the buoy is the strongest when the wave frequency is 0.33 Hz. The hydrodynamic parameters of the two-body are different from the corresponding parameters of the single body in some frequency ranges. The new wave energy generation device combined with the ocean buoy and the pendulum has a stronger energy harvesting effect when the wave frequency is less than 0.18 Hz.
