[Abstract]:The object of this paper is a floating wave power generation platform, which has been successfully tested in the sea area of Xiaodeng Island, Xiamen. The main task of this study is to optimize and transform the energy transfer system in the platform. The original mechanical transmission system was replaced by a two-stroke full-cycle hydraulic transmission system. The main research contents include the following aspects: firstly, the research status of several floating wave energy conversion devices and their optimization are briefly introduced, and the working principle and characteristics of the floating wave power generation platform are described. And the reason of transforming the mechanical transmission system into hydraulic transmission system. Secondly, through the study of Stokes wave theory and the modeling and simulation of the platform by the hydrodynamic software AQWA, the hydrodynamic parameters such as displacement, force and velocity of the float are obtained. The energy recovery efficiency of a single float under different wave conditions in four seasons, the power produced under specific wave conditions and the velocity at the output end of the float arm are calculated, which provides the basis for subsequent hydraulic system simulation. Thirdly, according to the hydraulic transmission system of the array wave power generation platform, the specific design requirements and solutions are put forward, and based on this, a two-stroke full cycle hydraulic transmission system is designed. According to the simulation results of the platform float by AQWA software, the motor with rated power of 5kW and the corresponding hydraulic components are selected. Finally, the hydraulic simulation software AMESim is used to model and simulate the hydraulic transmission system, to verify the feasibility of the system, and to analyze the system pressure, flow rate and motor torque by changing the relevant parameters. Dynamic characteristics of rotational speed and other parameters. The simulation results show that the pressure pulsation and flow pulsation of the hydraulic system are well absorbed after the accumulator's energy storage and the power generation meets the design requirements. The designed hydraulic transmission system matches well with the floating wave power generation platform.
