针对海洋监测活动的需求,提出运用一种新型的双浮体波浪能发电装置(WEC),并应用基于三维势流理论的有限元软件AQWA对装置的垂荡特性进行了频域分析,即采用无阻尼的质量弹簧系统共振理论对能量转换装置(PTO)刚度和阻尼进行优化,分析了入射波浪频率和浮体初始吃水深度对装置的影响。结合我国渤海区域特定波况取相似因子为1∶15,对该双浮体波浪能发电装置进行了模型设计,并在华南理工大学造波水池进行试验,结果显示该装置在规则波作用下俘获宽度比达1.433,具有实际应用意义。
Aiming at the demand of marine monitoring activities, a new type of double buoyant wave power generator (WEC) is proposed. The heave characteristics of the device are analyzed in the frequency domain by using finite element software AQWA based on three-dimensional potential flow theory. The Nyquist mass-spring-system resonance theory is used to optimize the stiffness and damping of the energy conversion device (PTO). The effects of the incident wave frequency and the initial draft of the float on the device are analyzed. Based on the similarity factor of 1:15 in the specific wave regime in the Bohai Sea region of China, a model design of the double-buoyant wave power plant was carried out. The experiment was carried out in a wave-making basin of South China University of Science and Technology. The results showed that the device captured the width Ratio of 1.433, with practical significance.
