| Abstract: | Based on the potential theory, a 3D frequency-domain model is set up for the simulation of wave interaction with pendulum wave energy converters (WECs). Hydrodynamic analysis is carried out for characteristic parameters of two WECs with different mass, and optimism power take-off (PTO) torsional damping coefficients in consideration of viscous damping actions are obtained. Then on the foundation of the above best condition, systematic examination is carried out for the influence of incident wave frequency on body response and captured wave energy, and the optimism wave frequency ranges, amplitude, capture efficiency and fluctuating pressures on the pendulum plates are simulated. |

| Keywords: | wave energy converter pendulum hydrodynamic characteristic frequency￣domain model fluctuating pressure capture efficiency |
