The modal analysis of the conical tube tower for wind turbine

TLDR: In this article, a 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 not.

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
