Vibration suppression for high speed railway bridges using fluid viscous dampers [PDF]

MATEC Web of Conferences, 2019
The results of experimental and theoritical investigations of railway bridges have shown the significant dynamic responses exceeding that anticipated on certain railway bridges, such as a resonance phenomenon who have a great effect in the bridge ...

Prediction of the Ability of a Viscous Fluid Damper with Respect to Change of the Size of the Damper

Transactions of the Korean Society for Noise and Vibration Engineering, 2012
To reduce the vibration in industrial settings, the viscous fluid dampers have been widely used. Since the damper shows a viscoelastic behavior, many methods to predict the behavior have been investigated. But the methods did not consider a change of damper size that is important factor for practical design engineer.

Using a damper amplification factor to increase energy dissipation in structures [PDF]

, 2015
Fluid dampers are an important tool for dissipating unwanted vibrations in a range of engineering structures. This paper examines the effects of amplifying the displacements transferred to a non-linear damper, to increase the effectiveness of the damper ...

Multi-Span Steel–Concrete Bridges With Anti-seismic Devices: A Case Study

Frontiers in Built Environment, 2019
Seismic protection for structures in general, and bridges in particular, is very complex. Indeed, any analysis of bridges with fluid viscous dampers and shock transmitting devices must be completed using a sophisticated finite element (FE) model ...

Study on viscous-friction series damper for industrial facilities (Mechanism and basic performance of damper)

Nihon Kikai Gakkai ronbunshu, 2016
This study proposes a viscous-friction series damper. The series damper consists of an oil damper and a friction damper connected in series. Long period and long time seismic waves were recognized as new problems by the Great East Japan Earthquake.

A Two-Dimensional Axisymmetric Finite Element Analysis of Coupled Inertial-Viscous-Frictional-Elastic Transients in Magnetorheological Dampers Using the Compressible Herschel-Bulkley Fluid Model

Frontiers in Materials, 2019
It has been challenging to accurately predict the unique characteristics of magnetorheological (MR) dampers, due to their inherent non-linear nature.

Use of viscous fluid dampers for the improvement of the seismic response of RC structures [PDF]

Vibroengineering Procedia, 2019
Earthquake resistant design requires the knowledge of strategies to minimize the effects of the seismic load onto the structural response. In this paper, the implementation criteria of nonlinear viscous fluid dampers (VFD), in diagonal configuration is discussed. Two different values in the damping exponent (
