Optimum design of a novel pounding tuned mass damper under harmonic excitation

Smart Materials and Structures, 2017
In this paper, a novel pounding tuned mass damper (PTMD) utilizing pounding damping is proposed to reduce structural vibration by increasing the damping ratio of a lightly damped structure. The pounding boundary covered by viscoelastic material is fixed right next to the tuned mass when the spring–mass system is in the equilibrium position. The dynamic

Vibration control of vortex-induced vibrations of a bridge deck by a single-side pounding tuned mass damper

Engineering Structures, 2018
Abstract This paper proposes a new method to mitigate vortex-induced vibrations (VIVs) of a bridge deck using a single-side pounding tuned mass damper (SS-PTMD). The SS-PTMD is a passive control device and comprises an undamped tuned mass with a pounding boundary covered with viscoelastic (VE) materials layer.

Pounding tuned mass damper with constrained layer damping

Advances in Structural Engineering, 2023
The pounding tuned mass damper (PTMD), which is a passive vibration control device, has attracted much attention in recent years. However, due to the absence of additional dampers in traditional PTMD, the free vibration of structures cannot always be suppressed quickly.

A Computationally Efficient Method for Optimum Tuning of Single-Sided Pounding Tuned Mass Dampers for Structural Vibration Control

International Journal of Structural Stability and Dynamics, 2021
Pounding tuned mass dampers (PTMD), which relies on impact to dissipate vibration energy, have shown remarkable performance in suppressing structural vibrations with its modest design. However, the optimum design of PTMDs is computationally expensive due to non-smooth contact-impact behavior. This study provides a computationally efficient approach to
