摘要：

A power take-off oil-hydraulic system is designed for an oscillating wave surge converter. The adaptation of the converter to the power take-off is performed with genetic algorithms in order to find out the optimal geometrical and control parameters, while different power take-off layout configurations are simulated to maximize their efficiency. The simulations show that the power take-off of the oscillating wave surge converter is more effective and efficient, because the converter is driven by bigger excitation wave moments, rather than the resonant characteristics of the point absorber converter, and on the other hand, allows a less constrained design optimization of the mechanical interface with the power take-off. It was verified that these key features allow the production of lower oil flowrates at higher pressure levels, lower oil flow speeds at the cylinder ports and lower ratios between hydraulic peak and averaged power, thus characteristics that must be found in an efficient and effective power take-off.
