In order to achieve the efficient utilization of offshore wind and wave resources, a numerical model of the combined system is established based on Windfloat wind turbine platform combined with rocker wave energy converters, and the effects of key parameters such as wave period, PTO (Power take-off) damping, buoy diameter and rocker length on the motion and energy acquisition of the combined system are analyzed. It is found that with the increase of wave period, the overall motion response of the platform tends to increase, and the energy acquisition of the converters increases first and then decreases;with the increase of PTO damping, the surging and pitching motion of the platform gradually decreases, the heaving motion of the platform and the energy acquisition of the converters increases first and then decreases;with the increase of buoy diameter and rocker arm length, the surging motion response of the platform decreases gradually, heaving and pitching motion response increase gradually, the energy acquisition of the converters increases with the increase of buoy diameter, and increases first and then decreases with the increase of rocker arm length.
