Abstract

In this paper, a self-sustaining wave energy device with heave attitude is proposed, and the motion equation of the device is established. Based on the potential flow theory, the hydrodynamic analysis numerical model is constructed and verified. The constant and linear PTO are loaded, the power generation and capture width ratio are calculated, and the parameters are optimized. The results show that when other parameters remain unchanged, the average output power and capture width ratio of the device increase first and then decrease with the increase of PTO, the radius and draft of the float, the length of the horizontal bar and the inclination angle of the horizontal bar, while the increase of the mass ratio of the float to the horizontal bar has little effect. When the length ratio of the horizontal and vertical rods is 0.5, that is, the length of the horizontal rod is 4.8 m, the average output power and capture width ratio of the device are the largest. When the inclination angle of the crossbar is 40°, the device has the best energy acquisition effect.
