In order to improve the energy capture efficiency of a multi-pendulum wave energy converter, a mathematical model of the pendulum structure has been built. The final structure parameters of the pendulum have been obtained by using genetic algorithm based on the numerical simulation results of the pendulum structure optimization. The results show that under obtained structure parameters the proposed multi-pendulum device can obtain maximum energy conversion efficiency.

Based on the three dimensional potential theory, numerical studies were carried out to investigate the hydrodynamics of a single-acting trapezoidal pendulum wave energy converter in regular waves by using time domain analysis. The nonlinear viscous damping was also taken into account, and the influence of power take-off damping on the motion responses and output performances were analyzed. Comparisons of experimental and numerical results were performed as part of the validation process.
