The world’s environmental pollution is more and more serious, and the human society for the energy demand is more and more large, so o the research of clean new energy is very necessary. In this paper, flow-3D software is used to simulate and study the motion state, velocity, kinetic energy, wave force and amplitude of cone and cylinder floats under different masses with the same wave height, so as to obtain the influence of mass on wave absorption efficiency and output power of these two kinds of floats. The results show that :(1) when the wave height is 0.25m, the wave energy absorption efficiency of the cylindrical and conical float increases first and then decreases with the increase of mass. The absorption efficiency of the 6kg cone float is the best, which is 27.77%. (2) With the increase of mass, the output work of the conical float firstly increases and then decreases, and reaches its maximum value at 6kg, which is 1.27w.

Study on the influence of float parameters on the efficiency of oscillating float wave power generation
