ADVANCED OPTIMIZATION PROCESSES FOR THE DESIGN OF 3D-PRINTED METAL DAMPERS

Proceedings of the 8th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2023
Over the past years, the research field concerning the passive seismic protection of buildings gained relevance more and more, due to the severe earthquakes affecting several parts of the world, often hitting very populous areas. Meanwhile, recent additive manufacturing technologies allowed the implementation of innovative metal passive protection ...

Study of an innovative graded yield metal damper

Journal of Constructional Steel Research, 2019
Abstract Metal dampers have been widely used to improve the seismic performance of the building structure. However, conventional metal dampers only possess one yield point and cannot protect the structure efficiently under earthquakes of different intensities.

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 ...

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.

Experimental study of structure with “dual function” metallic dampers

Engineering Structures, 2007
Abstract A type of dissipative device referred to as a “dual function” metallic damper was presented in this paper. These types of metallic dampers are referred to as “dual function” metallic dampers (DFMDs), because they provide additional structural stiffness, and also have fairly good seismic energy-dissipation capabilities.
