Optimal tuning of the tuned mass damper (TMD) for rotating wind turbine blades

Engineering Structures, 2020
Abstract This paper presents the explicit formulas for optimal tuning of the tuned mass damper (TMD) for damping edgewise vibrations in rotating wind turbine blades. A 2-DOF model is first established for the rotating blade-TMD system, which acts as the basis for analytically deriving the optimal frequency-tuning and the optimal damping-tuning ...

Negative stiffness enhanced tuned mass damper (NS-TMD) for seismic induced response mitigation of isolated bridges

Engineering Structures
Seismic isolators have been extensively utilized in the field of structural vibration control due to their superior control effectiveness in reducing absolute acceleration responses. However, this effectiveness comes with compromise on large isolating deformation, which may result in various issues, such as pounding and/or unseating damages of bridge ...

Improvement of tuned mass damper by using rotational inertia through tuned viscous mass damper [PDF]

open access: yesEngineering Structures, 2013
A new vibration control device called a rotational inertia double-tuned mass damper (RIDTMD) is proposed in this paper. The device consists of a tuned mass damper (TMD) in which the typical viscous damper is replaced with a tuned viscous mass damper. The

On Stochastic Design of Negative Stiffness Integrated Tuned Mass Damper (NS-TMD)

Journal of Vibration Engineering & Technologies, 2021
The negative stiffness integrated tuned mass damper (NS-TMD) is considered as an interesting and efficient device for passive vibration control. However, design/optimization of NS-TMD may not always lead towards robust performance if there exist uncertainties. In this study, a stochastic design of NS-TMD is proposed taking into account various types of
