Abstract
In order to predict the dynamic strain of offshore wind turbine towers under wind loading,modal decoupling equa-tions are derived based on modal theory.The decoupled vibration equations are solved using Duhamel integration,and the system re-sponse is obtained by superimposing the solutions.A tower model is established using finite element software for numerical simula-tion,and the displacement modal and strain modal shapes of the tower are analyzed.The tower displacement and strain at rated wind speed are simulated,and modal coordinates are calculated based on displacement and strain measurement points.The modal super-position method is then applied to predict tower strain.Comparative analysis reveals higher accuracy in modal coordinates calculated based on displacement measurement points,validating the feasibility of predicting dynamic strain in wind turbine towers using the modal superposition method.关键词
