Abstract

In order to study the influence of wind turbine blade and the blade centrifugal stiffening effect on natural vibration characteristics of wind turbine tower, the finite element model of wind turbine tower was established. By calculating the axial force under the rotating state of the blade, the additional stiffness caused by the centrifugal stiffening effect of the blade was obtained. The natural vibration properties of wind turbine tower structure under three conditions were calculated and the natural frequencies were compared. The results show that the influence of the blade makes the natural frequency of the wind turbine tower structure decreased and the natural frequency of the wind turbine tower structure considering the centrifugal stiffening effect is higher than that not considering the centrifugal stiffening effect. Therefore, it is necessary to consider the influence of the blade and the blade centrifugal stiffening effect on the dynamic characteristics analysis of the wind turbine tower structure.
