| Abstract: | The motion equations of oscillating buoys are established based on the potential flow theory, and different shape buoys shapes are modeled to simulate and calculate the hydrodynamic properties of the single float in the frequency domain. AQWA is mainly used to compare the effect of the bottom shape, diameter, draft, center of gravity position of buoys on the RAO, wave excitation force, radiation damping, added mass. The results are compared with that of previous study. It is found that the performance of the cylindrical bottom of the float is excellent, and the changes of the center of gravity have less effect on heaven motion than the effect of damping and the radius of buoys, which provides the guide for the structure optimization and array analysis of the floats. |
