This paper proposes a novel, simple and high-efficient submerged structural stabilization system for a self-stabilizing buoy that provides a stable platform for oceanographic and meteorological sensors. The proposed stabilization system is a Seesaw-like Tuned Mass Damper (STMD) combined with a foil and is designed in a way to harvest the activation energy from incoming waves. A fixed rudder in the rear underside of the buoy, as well as physical properties of the buoy, help to keep its balance in yaw and roll directions while encountering lateral waves. Therefore, the orientational stabilization of the whole structure is achieved by controlling only the pitch deviation. The proposed model is then simulated in a marine dynamic analysis software. Two different shapes of a thin rod and a foil were proposed for the sliding mass (slider) of the STMD and their performances are investigated and compared to each other in two different modes of passive and active control. In the passive mode, different mass ratios were conducted for the thin rod-shaped slider (i.e., a ratio of the effective mass of the stabilizing system to that of the whole structure) and a mass ratio of 8% could suppress the pitch deviation up to 81.3% in the resonance condition. The same STMD system with a mass ratio of 2% suppresses the pitch deviation by only 7%. In the active mode, the STMD with a thin rod-shaped slider and a mass ratio of 8% exhibits only 49.1% suppression effect in a multiwave condition. However, by changing the shape of the slider to a foil while controlling its angle of attack (AOA) mechanically, the system with the mass ratios of 2% and 8% could suppress the pitch deviation of the buoy up to 69.4% and 79.1%, respectively.

使用移动箔的天气浮标结构稳定系统的设计，评估和评估

本文提出了一种新颖，简单，高效的水下自稳定浮标结构稳定系统，为海洋和气象传感器提供了稳定的平台。拟议的稳定系统是一种类似跷跷板的调谐质量阻尼器（STMD），其与金属箔结合使用，并且设计为从入射波中收集激活能量。浮标后下部的固定舵以及浮标的物理特性有助于在遇到侧向波时保持其在偏航和侧倾方向上的平衡。因此，通过仅控制间距偏差来实现整个结构的取向稳定性。然后在海洋动力学分析软件中对提出的模型进行仿真。提出了两种不同形状的细杆和金属箔用于STMD的滑动质量（滑块），并在两种不同的被动和主动控制模式下研究了它们的性能并进行了比较。在被动模式下，对细杆形滑块进行不同的质量比（即稳定系统的有效质量与整个结构的有效质量之比），并且质量比为8％可以抑制螺距偏差在共振条件下达到81.3％。质量比为2％的相同STMD系统仅可将音高偏差抑制7％。在主动模式下，具有细杆状滑块且质量比为8％的STMD在多波条件下仅表现出49.1％的抑制效果。但是，通过将滑块的形状更改为箔片，同时机械地控制其迎角（AOA），
