Control of flapwise vibrations in wind turbine blades using semiactive tuned mass dampers
The increased size and flexibility of modern multi-Megawatt wind turbines has resulted in the dynamic behaviour of these structures becoming an important design consideration. The aim of this paper is to study the variation in natural frequency of wind turbine blades due to centrifugal stiffening and the potential use of semi-active tuned mass dampers (STMDs) in reducing vibrations in the flapw...
متن کاملSemiactive Tuned Mass Dampers
Studies have already demonstrated the successful use of linear semiactive damping devices, such as variable orifice (VO) dampers, for semiactive TMD systems. More recently, nonlinear semiactive damping devices, such as magnetorheological (MR) dampers, have also been shown to be effective for semiactive control of TMDs. Though semiactive dampers differ widely, with responses ranging from linear ...
متن کاملDynamic response mitigation of floating wind turbine platforms using tuned liquid column dampers.
In this paper, we experimentally study and compare the effects of three combinations of multiple tuned liquid column dampers (MTLCDs) on the dynamic performance of a model floating tension-leg platform (TLP) structure in a wave basin. The structural stability and safety of the floating structure during operation and maintenance is of concern for the performance of a renewable energy device that...
متن کاملWind Turbine Tower Resonance
Wind turbine towers are large structures designed to withstand the unique loading conditions imposed on them by the turbine’s nacelle and dynamic forces from the rotating blades. Observations and noise measurements of a particular wind turbine showed high noise levels at approximately 48 Hz, which could not be explained from the usual known potential noise sources. Correlated far field noise me...
متن کاملreducing the seismic response of nonlinear hysteretic structures using optimal multiple tuned mass dampers
in this research, the effectiveness of multiple tuned mass dampers (mtmds) in mitigating the response of nonlinear hysteretic structures has been studied where the optimal parameters of mtmds have been determined based on minimization of maximum relative displacement (drift) of structure. for solving the optimization problem the genetic algorithm (ga) has been used successfully. for numerical a...
