Study on SMA Pseudo-Rubber Metal Damper

Advanced Materials Research, 2011
In this paper, Shape Memory Alloy (SMA) Pseudo-Rubber Metal (PRM) was studied, and comparative test with common Pseudo-Rubber Metal was carried out. The enveloped area of hysteresis curve of SMA PRM is clearly larger than that of common PRM, which indicates the damping of SMA PRM overmatches that of common PRM. The stiffness value of SMA PRM and common

Experimental Evaluation of a Metal Mesh Bearing Damper

Journal of Engineering for Gas Turbines and Power, 1999
Metal mesh is a commercially available material used in many applications including seals, heat shields, filters, gaskets, aircraft engine mounts, and vibration absorbers. This material has been tested by the authors as a bearing damper in a rotordynamic test rig.

Design of Metallic Dampers and Analysis Using MATLAB Program

ASPS Conference Proceedings, 2022
Earthquakes are one of the major natural hazards to life on the earth and have affected countless areas on almost every continent. The damaged caused by earthquakes are mostly seen in man-made structures which are most of the time responsible for most of the causalities.

Study on mechanical characteristics of accordion metallic damper

Journal of Constructional Steel Research, 2018
Abstract This paper presents Accordion Metallic Damper (AMD) as a unique energy dissipating system that originated from the concept of thin-walled tubes used in machinery as the shock absorber. The AMD can perform as a repairable hysteretic fuse in structural frames to enhance the lateral ductility, energy-dissipation and damping potential of the ...

Optimization of additively manufactured metal dampers

14th International Conference on Structural Safety and Reliability
This paper presents a novel typology of metallic energy dissipation device (damper) for seismic protection of buildings, distinguished by its capacity to independently modulate strength and stiffness parameters. This objective is accomplished through the implementation of non-standard geometries, enabled by advanced additive manufacturing techniques ...

U-shaped metallic-yielding damper in building structures: Seismic behavior and comparison with a friction damper

Structures, 2015
Abstract This paper presents the performance of U-shaped metallic-yielding dampers in steel building frames as well as a comparison with rotational friction dampers, known as Friction Damper Devices (FDD). For this purpose, an installation detail to use a U-shaped damper in steel building frames was suggested.

Shear Performance of a Metal Foam Magnetorheological Fluid Damper

IEEE Transactions on Magnetics, 2015
This paper mainly investigates the shear performance of a metal foam magnetorheological (MR) fluid damper. As for the damper, MR fluids are stored in metal foam in the action of magnetic field, MR fluids are drawn out from the metal foam, and then fill the shear gap, thus producing the MR effect.

Semi‐active control of metal foam magnetorheological damper

Materialwissenschaft und Werkstofftechnik, 2021
AbstractA new type of foam metal magnetorheological damper is designed, and its performance in semi‐active control is investigated. At first, magnetorheological fluid is stored in the pore of metal foam, and with the action of magnetic field, magnetorheological fluid is extracted from metal foam, and then fills up the shear gap to produce ...

Cyclic behavior of shear-and-flexural yielding metallic dampers

Journal of Constructional Steel Research, 2015
Abstract The energy dissipation potential of a metallic damper largely depends on the hysteretic response achieved due to the inelastic deformation of plates under either axial or flexural or shear loading. In this study, a passive energy dissipation device consisting of a series of steel plates capable of yielding in both flexure and shear has been ...

Experimental and numerical evaluation of piston metallic damper (PMD)

Journal of Constructional Steel Research, 2019
Abstract In this paper, a metallic yielding damper, called piston metallic damper (PMD) is introduced for the first time. The PMD is comprised of a set of parallel hollow circular plates that interconnect inner shaft of the PMD to its outer pipe. Experiments and numerical models are used to examine its applicability as a seismic energy dissipating ...
