Analysis of a Two-Degree-of-Freedom Vibration System Model of an Oscillating water column wave energy converter installed on a double-slit breakwater

Abstract

Breakwaters protect beaches by absorbing wave energy. Double-slit breakwaters can be used as air chambers for oscillating water column wave energy converters. In this study, the oscillating water column-type wave power generator using the double-slit breakwater was treated as a two-degree-of-freedom oscillating system model. The differential equations of motion were derived from Newton's second law, and the frequency response characteristics of the vibration of the oscillating water column- type wave energy converter using the double-slit breakwater were investigated using Simulink in MATLAB.
