Research on Dynamic Behaviour of Wind Tower under Ambient Excitation Based on DASP
By means of site test of horizontal-axis wind turbine tower under different working conditions, the paper make a further analysis by DASP system and obtained the acceleration spectrum and characteristic frequency; Again to build finite element model of the tower and calculated it's dynamic characteristics. The measured results and calculative results provide a basis for avoiding resonance and further study of structure dynamic response of wind turbines tower; In addition, it can provide valuable modal parameter data for wind tower design and structural vibration control.
