| 根据布设海域波浪能资源特征，对点吸收式波浪能装置结构进行优化，可有效提高装置的能量俘获效率。本文以威海褚岛北部海域为装置布设目标海域，在对该海域波浪资源特征进行统计分析的基础上，计算得到装置的直径，同时利用数值软件计算出多组工况下点吸收装置吃水深度和装置固有周期的对应关系，并利用统计学方法得出装置固有周期随吃水深度的变化规律，进而分析得出装置在该海域的最佳设计吃水深度，为点吸收波浪能装置结构优化设计提供了新的思路。该方法对于其他技术类型波浪能装置的结构优化设计同样具有借鉴意义。 |

| Abstract: |
| According to the characteristics of wave energy resources in a sea area, the energy capture efficiency can be effectively improved by optimizing the structure of the point absorption device. Based on the statistical analysis of the characteristics of wave resources in the north area of Chudao Island, Weihai, Shandong, East China, the diameter of the device, the corresponding relationship between the draft of point absorption device, and the natural period of the device under multiple working conditions were calculated using numerical software, and the variation of the natural period of the device with the draft was understood by using a statistical method. The optimal design draft of the device in the sea area was determined, which provides a new idea for the structural optimization design of the point absorbing wave energy device. This method can also be used for reference in the structural optimization design of other types of wave energy devices. |
