RESEARCH ON RESPONSE AND POWER PRODUCTION OF HORIZONTAL ECCENTRICPENDULUM WAVE ENERGY CONVERTER
In this article,the horizontal eccentric pendulum wave energy converter with single and multiple degrees of freedom are characterized through numerical simulations and model tests.Three states of the pendulum's motion are observed at different wave periods including small amplitude oscillation,pure rotation,and oscillating rotation.It is noted that the pendulum has a"lock-up"phenomenon in the device with a single degree of freedom,while in the multi-degree of freedom the pendulum can avoid such phenomenon and performs better.There are two peaks of the average power with respect to the wave period.The first peak is positively correlated with PTO damping,and its period is positively correlated with the PTO damping and the swing arm length.The second peak and period are both positively correlated with the axis ratio of outer float.
