The tower of onshore wind turbine is the supporting part of the whole machine, and its service is related to the safety state of the whole machine. In order to ensure the safety of the whole machine operation, the vibration analysis of the tower is needed. This paper takes the onshore wind turbine tower as the research object, establishes the 3D model of the onshore wind turbine tower, and uses Ansys Workbench software to carry out the finite element modal analysis of the tower. According to the results of finite element modal analysis, the measured scheme is designed to test the tower, and the measured data onto tower vibration is analyzed by power spectrum. The analysis results can provide some reference to vibration monitoring of wind turbine tower.
