ABSTRACT

Wave energy is an important clean renewable energy source for the ocean, and is of great importance for development. However, it is difficult to achieve the unity of high efficiency and high reliability of existing wave energy development devices. In this paper, a new form of fully enclosed eccentric pendulum wave energy generation device is proposed. A hydrodynamic model based on AQWA software, a mechanism dynamics model based on Adams software, and a hydraulic energy conversion system model based on AMESim software are developed to analyze the motion response and power generation performance of the device under different wave excitation conditions. The results show that the wave excitation conditions and the rotor eccentricity jointly affect the power generation performance of the wave energy generation device, and the high efficiency of wave energy capture can be obtained by real-time adjustment of the rotor eccentricity. This paper both exploits the high reliability of the fully enclosed structure and proposes a control strategy to achieve efficient energy conversion, laying the foundation for the development of a wave energy generation device with both high efficiency and high reliability.
