Abstract:As an important component of the wind turbine, the tower has a harsh working environment and complex stress, and the load it bears is highly random and variable. Its dynamic characteristics directly affect the safe operation of the wind turbine. Higher requirements are placed on the dynamic characteristics, life loss characteristics and stability of tower. The engineering background of wind turbine tower dynamic characteristics and structural loss research were described, the tower structure and main load characteristics of large-scale wind turbines were introduced, the more common tower structure model establishment methods and working condition simulation methods were sorted out, and the research progress of tower structure modal analysis, dynamic response analysis, buckling stability analysis, and fatigue damage analysis were summarized. Additionally, the domestic and foreign numerical values of simulation technology and the research results were reviewed. A preliminary prospect for the future research direction of tower dynamic characteristics was also made, aiming to provide some references for the further development of this research field.
