A Hybrid Damper with Tunable Particle Impact Damping and Coulomb Friction

Machines, 2023
A particle impact damper (PID) dissipates the vibration energy of a structure through impacts within the damper. The PID is not commonly used in practice mainly because of its low damping-to-mass ratio and the difficulty in achieving its optimal design ...

Characteristics of the asymmetric Stockbridge damper [PDF]

MATEC Web of Conferences, 2021
The Stockbridge damper (tuned mass absorber) is used on overhead transmission power lines to suppress wind-induced vibrations. These power lines get exposed to various types of wind motions that cause them to vibrate and this causes fatigue failure at ...

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.
