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

Parametric study of pounding tuned mass damper for subsea jumpers
Smart Materials and Structures, 2015In previous study, a pounding tuned mass damper (PTMD) was proposed to reduce the undesired vibration of a subsea jumper. Both experimental and numerical results verified the effectiveness of the PTMD. This paper aims to enhance the understanding of the PTMD through a parametric study.

Numerical modeling and experimental study on a novel pounding tuned mass damper
Journal of Vibration and Control, 2017Owing to its easy implementation and robustness, the pounding tuned mass damper (PTMD), which uses viscoelastic materials to cover the pounding boundary to increase the energy dissipation during impact, has been studied in recent years. The conventional PTMD design includes a gap between the pounding mass and the viscoelastic material; the value of ...

This paper discusses the pounding tuned mass damper (PTMD) — a novel device developed in a joint collaboration between OneSubsea, a Schlumberger Company and the University of Houston to absorb and dissipate the undesired vibrations generated due to VIV and FIV in subsea pipeline and jumpers. The PTMD is based on principles of both the tuned mass damper

Practice Periodical on Structural Design and Construction, 2023
Pounding between adjacent buildings subjected to ground motion excitation is one of the most dangerous phenomena for building safety. In this paper, three novel configurations are proposed (two of them are uncoupled, and one of them is coupled), and two different passive devices are used, namely, tuned mass damper inerter (TMDI) and tuned inerter ...

Optimum design of a novel pounding tuned mass damper under harmonic excitation
Smart Materials and Structures, 2017In 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

Robustness study of the pounding tuned mass damper for vibration control of subsea jumpers
Smart Materials and Structures, 2015A previous study by the authors proposed a new type of damper, the pounding tuned mass damper (PTMD), which uses the impact of a tuned mass with viscoelastic materials to effectively dissipate vibration energy, for structural vibration control. However, the control performance is unknown if the PTMD is not tuned to the targeted frequency of the primary
