Abstract
This study is concerned about the motion of the floating wind turbine. Floating wind turbine stands in the ocean, and it encounters the wind loads and wave loads. When the wave hits the floating platform, the floating platform begins to do some kinds of motion. This study supposes that the floating wind turbine hit by regular wave begin to do pitching, surging, and heaving motions. By calculating the inertial force induced by the motion of platform, the stress on the blade can be analyzed. Conduct an experiment to measure the stress on the blade when the tower is doing the pitching motion. Besides, the motion of the wind turbine influences the power efficiency. Therefore, this study uses BEM method to calculate the power generation of the wind turbine when the platform is doing pitching motion.
