Research On Dynamic Behaviour Of Wind Tower Under Ambient Excitation Based On DASP

摘要

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.
