Abstract: Aiming at the problem that wave power generation system has serious corrosion and large impact in marine environment, the physical model, electric energy conversion, magnetic field lines and magnetic flux distribution of a fully enclosed linear wave power generation system was studied. The change of electromagnetic damping in the system which leads to the variation of dynamotor displacement amplitude was analyzed. Therefore, a linear wave generation system based on forced vibration of single degree of freedom was proposed. Based on Ansoft, magnetic field of the linear wave power generation system was simulated. The motion of dynamo was analyzed by using Forced Vibration of Single degree of freedom model. Wave pool was used to carry on qualitative experiment of this system. The results indicate that the whole sealed way of linear wave power generation system can solve the serious problem of corrosion for power generation part and the controllability of dynamo displacement amplitude reduces the impact of system. Magnetic field lines and magnetic flux distribution is uniform. The system can follow wave oscillation.

Key words: forced vibration of single degree of freedom; wave power generation; Ansoft simulation
