ANALYSIS OF DYNAMIC CHARACTERISTICS OF 1.5 MW WIND TURBINE TOWER

摘要：

　　The wind turbine tower is to bear wind load and work load which is brought by the rotating blades during operation.Therefore,analysis of dynamic characteristics of wind turbine tower is a complicated task in the wind turbine reliability design.The dynamic characteristic of wind turbine tower plays an important role in its vibration control.This paper presents fluid-structure coupled dynamics equations accounting for the blade wheel load and wind load applying on the tower.By the model analysis,a feasible method for evaluating the dynamic characteristics of wind turbine tower under the wind turbine wind load and the rotating blade random load is obtained.The model is verified in the 1.5MW wind turbine.
