The design of maximum output power of wave energy device is studied.Based on the theoretical background of motion balance equation and energy output system research,the heave and pitch motion model and the optimal damping coefficient model of float and vibrator are established.The heave displacement and velocity and pitch displacement and angular velocity of the float and vibrator at a given time are determined.The maximum output power and the optimal damping coefficient under the given parameter values are determined by simulated annealing algorithm and grid search algorithm respectively for two situation.
