论文摘要
本文提供了对带有液压功率（PTO）系统的皮瓣型波能转化器的研究。这项研究包括衍生其运动方程以及对设备的固有频率的分析。使用可填充的圆柱体构建了原型，并在波浪水槽中进行了一系列实验。在这些实验中，更改了液压回路的压力值，以研究系统在一系列波周期内压力的最佳值。在广泛的波周期内，达到了平均波到流体效率（约15％）。还发现，可以达到26％的波到流体效率，以达到6.71 s的波浪。根据这项分析研究的结果，可以通过用海水填充其隔室来进一步优化该设备。
This paper provides a study of a flap-type wave energy converter with a hydraulic power-take-off (PTO) system. This study includes the derivation of its equation of motion along with an analysis of natural frequencies of the device. A prototype was built using fillable cylinders and a series of experiments were performed in a wave flume. In these experiments, the pressure values of the hydraulic circuit were changed to investigate the optimal value for the system's pressure for a range of wave periods. The average wave-to-fluid efficiency (of about 15%) was achieved for a broad range of wave periods. It was also found that a 26% wave-to-fluid efficiency can be reached for waves with a period of 6.71 s. Based on the results of this analytical study, this device can be further optimized by filling its compartments with seawater.
