Seismic control performance for Pounding Tuned Massed Damper based on viscoelastic pounding force analytical method

Journal of Sound and Vibration, 2017
Abstract This paper focuses on vibration control performance of Pounding Tuned Massed Damper (PTMD) with viscoelastic pounding layers, which can dissipate energy during collision process. By using of viscoelastic pounding force analytical method, two types of pounding force models for different contact geometries are developed to illustrate ...

Pounding Tuned Mass Damper (PTMD): An Innovative Damper for Subsea Pipeline and Jumper Vibration Controls

ASME 2017 India Oil and Gas Pipeline Conference, 2017
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

Numerical modeling and experimental study on a novel pounding tuned mass damper

Journal of Vibration and Control, 2017
Owing 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 ...

Effectiveness of Optimal Shared Multiple Tuned Mass Damper Inerters for Pounding Mitigation of Adjacent Buildings

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 ...

Vibration Control of a Pipeline Structure Using Pounding Tuned Mass Damper

Journal of Engineering Mechanics - ASCE, 2016
AbstractPipeline structures are often very flexible and susceptible to vibrations induced by many sources, such as vortex, external flow, and internal fluid flow. The pounding tuned mass damper (PTMD) is one device that may be employed to absorb and dissipate these undesired vibrations.

Multiple Pounding Tuned Mass Damper (MPTMD) control on benchmark tower subjected to earthquake excitations

Earthquakes and Structures, 2016
To explore the application of traditional tuned mass dampers (TMDs) to the earthquake induced vibration control problem, a pounding tuned mass damper (PTMD) is proposed by adding a viscoelastic limitation to the traditional TMD. In the proposed PTMD, the vibration energy can be further dissipated through the impact between the attached mass and the ...
