In order to investigate the motion response rule of tension leg platform(TLP)floating wind turbine(FWT)and quickly obtain the dynamic response characteristics of the FWT,and to guide the FWT to carry out the research work of conceptual design.The TLP wind turbine proposed by the National Renewable Energy Laboratory(NREL)is taken as the research object,and a three-degree-of-freedom simplified theoretical model is established based on the derivation of the Euler-Lagrange dynamic equation.The theoretical solution of the displacement response of the simplified model is solved and compared with the numerical simulation results of OpenFAST to verify the accuracy of the simplified theoretical model.The results show that the simplified theoretical model can improve the efficiency of the response solution and ensure the accuracy in the small motion amplitude range of TLP FWT.Through the established simplified model,the dynamic response characteristics of the TLP FWT structure can be obtained quickly,which can provide reference for the future research in disaster prevention and mitigation and vibration control of marine structures.
