碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 106 / Offshore wind turbine has been a popular topic in recent years, in order to cope with possible energy crisis in the future, every country in the world has set up offshore wind farms to replace power plant such as thermal power and nuclear power. This study is aim to the most common forms of foundations – monopole, and add a rigid frame system for numerical simulation, then use the form of hybrid system combined with the stiffness of the monopile foundation, to optimize and simulate analyze.
In order to probe into the offshore wind turbine under the environmental force, this study make use of the Newmark-β method to calculate the displacement, velocity and acceleration of wind force loads on the tower or the wave force loads on foundation. Wave force using empircal formula Morison Equation ,and the wind force is useing the design wind force by the structure of wind-resistant gauge theory.
This study combine the above method with the MATLAB (Matrix Laboratory) for matrix operation, and were aimed at offshore wind turbine foundation of three different forms to simulate. Under two kinds of wave and wind conditions, this study were evaluated the dynamic response with time of offshore wind turbine tower and foundation separately.
