The modal analysis of the conical tube tower for wind turbine

Abstract: The model of wind turbine tower was established by using the SAP2000 finite element analysis software,and the modal analysis of some wind turbine set was carried outThe relationships between the tower natural frequencies and the wind wheel rotational frequency were studied under conditions that the turbine tower has doorways or notSome foundational conclusions of the turbine tower was obtained by the discussion of the influencing factors of tower′s natural frequencyThe analytical results indicated that the doorways produce few influence on the tower′s natural frequency;there exists a decreasing linear relationship between the tower′s first-order natural frequency and the tower top quality;the tower′s low-order frequency plays a major role in determining whether to cause the tower and the wind wheel drive resonanceThis research may provide some reference for the design of wind turbine conical tube towers

Modal analysis of wind turbine tower

Abstract: As the support structure of wind turbine, the tower bears alternating loads of wind when the wind turbine runs. To ensure the reliability of the wind turbine, it's necessary to carry out modal analysis on the tower, and this would prevent the natural frequency of the tower close to the rated speed of wind turbine. In this paper, finite element analysis of the tower is solved using ANSYS, and the natural frequencies and modes of the tower are presented. After comparing the results of three models, a simple model for modal analysis, which can be calculated in short time, is finally determined.
