In this paper, a single-body point absorber system is analyzed to enhance its power absorption performance. The wave energy converter consists of a single floating body coupled to a direct-drive power takeoff system placed on the seabed. The geometry of a cylindrical buoy with large draft is modified, obtaining a particular geometry that is used to enhance the power absorption of the wave converter at a given site and at a finite depth. A numerical analysis tool (NEMOH) is used to obtain the buoy's frequency-dependent hydrostatic parameters; in addition, the buoy's dimensions are parameterized to tune the natural frequency of the oscillating system toward the frequency of dominant incident waves, thus enhancing wave power absorption for a specific wave frequency range. Furthermore, the damping influence of the power takeoff system on the performance of the wave energy converter is also considered.

点吸收波能转换器中的浮标分析

在本文中，分析了单体点吸收器系统以提高其功率吸收性能。波浪能转换器由一个单独的浮体组成，该浮体与放置在海床上的直接驱动动力输出系统相连。修改了具有大吃水力的圆柱形浮标的几何形状，获得了一种特定的几何形状，用于增强给定位置和有限深度的波转换器的功率吸收。数值分析工具（NEMOH）用于获得浮标频率相关的静水参数；此外，浮标的尺寸被参数化，以将振荡系统的自然频率调整到主要入射波的频率，从而增强特定波频率范围内的波功率吸收。此外，
