Abstract

The wave energy device moves under the drive of waves. During the movement of the device, the damper inside the device is driven to do work and the work done by the damper is converted into energy output.In this paper, the force of the system in the initial equilibrium state of the device is first analyzed, and then according to Newton's second law, the motion state of the float and the oscillator are analyzed separately, and the differential equation motion model of the float and the oscillator is established.When the constraints are damping coefficients, multiple search algorithms are used to solve them, and the negative work done by the linear damping force is obtained, with a period of 40 times as long. After the work is analyzed and discretized, the objective function expression is obtained, and a number of average output powers are obtained and continuously compared, and finally the maximum average output power and its corresponding parameter values are obtained.The optimal damping coefficient and the maximum average power are obtained.
