Abstract: This paper investigates vibration control for wind turbine blades that are subject to excessive wind-induced vibrations, which can lead to fatigue fracture. The study focuses on the application of tuned mass dampers (TMD). A finite element model of a wind turbine blade is developed in ANSYS Workbench, and modal analysis is performed to obtain the natural frequencies. The TMD parameters are designed using Den Hartog’s method for different mass ratios. Wind loads at rated wind speed are derived through fluid-structure interaction (FSI) simulations. Under these rated wind loads, simulation analysis of the blade was conducted in ANSYS. The results indicate that the TMD has a negligible effect on the static performance of wind turbine blades while effectively reducing blade vibration under wind loads. At different mass ratios, the achieved vibration suppression rates are 35.06%, 42.86%, and 46.75%, respectively. Under random wind speed conditions, transient dynamic analysis shows reduction rates of 30.41%, 44.62%, and 40.60% for the same mass ratios.
