Influence of Variable Damping Coefficient on Efficiency of TMD with Inerter
Energies, 2020 In this paper, we study the dynamics of a two-degree freedom system consisting of the main body and tuned mass damper with inerter (TMDI). We add the dash-pot with variable damping coefficient to TMDI to study the overall efficiency of the device.

A Comparison between a New Semi-Active Tuned Mass Damper and an Active Tuned Mass Damper
Procedia Engineering, 2011 AbstractReducing structural vibrations is one of the main concerns in structural control. Different control techniques are proposed for this purpose. Among the variety of control methods, semi-active ones are very attractive and beneficial in that they require minimum amount of energy but they are very capable to reduce structural displacements.
