Dynamic Analysis of The Wind Turbine Tower

摘要：

　　In this thesis,the conical tower of domestic popular 1.5MW wind turbine is analyzed in dynamic by using the software ANSYS.The natural frequencies can be extracted from the model analysis results,comparing them with the impeller rotational frequency and determining whether the tower will resonate when the wind turbine under normal operation conditions.Based on the model analysis,the transient dynamic analysis is carried out by inputting the history records of seismic wave acceleration,Both these two analysis can provide the basis for the safety evaluation of the tower.
