中文摘要:
      对振荡浮子式波浪能转换装置进行初步设计,并通过数值计算对装置结构进行优化,找出影响装置性能的主要因素,确定出在中国南海工况下装置性能最优的参数。结果显示,在中国南海常波周期5—6S附近,前港长Lfp和浮子长Lb对装置性能影响最大,是决定装置性能的主要因素;浮子吃水深度D和港内水深Dp是影响装置性能的次要因素,通过调整这两个参数,可在局部范围内改善装置性能;等深域水深H对装置性能几乎没有影响,建造装置选址时可不考虑这方面的因素。使装置性能最优的参数取值依次为:Lfp=4m,Lb=3m,D=2.5m,Dp=4.3m。
英文摘要:
      In this paper,a primary design of an Oscillating buoy wave power Device(OD) is conducted firstly,then a numerical calculation is carried out to find the main parameters that affect the performance of the OD,and find the optimal parameters of the OD when it works in South China Sea.The result shows that the length of the forepart of the port(Lf p) and the length of the buoy(Lb) are the primary parameters that affect the performance of the OD;the draft of the buoy(D) and the water depth in the port(Dp) are the secondary parameters,the performance of the OD can be improved partly by adjusting them;and the water depth in the region of constant depth(H) is irrelevant to the performance of the OD,It means that the water depth in the region of constant depth(H) can be left out of account when selecting a site to build the OD.The optimal parameters are shown below:Lf p=4 m,Lb=3 m,D=2.5 m,Dp=4.3 m around the usual wave period of 5-6 s in South China Sea.
