Effects of Diagonal Friction Dampers on Behavior of a Building

Applied Sciences, 2023
In this study, the effect of the friction damper location on the earthquake behavior of a building was investigated. Diagonal braced friction dampers were placed on different floors, and the changes in building behavior were examined. For this purpose, a

Numerical simulation of oscillations of a nonlinear mechanical system with a spring-loaded viscous friction damper [PDF]

MATEC Web of Conferences, 2019
The dynamics of a mechanical system consisting of a parallel-connected main elastic element, an external disturbance compensator having a nonlinear force characteristic, and a viscous friction damper sprung by a linear spring are studied.

Movers and shakers: Granular damping in microgravity

, 2010
The response of an oscillating granular damper to an initial perturbation is studied using experiments performed in microgravity and granular dynamics mulations. High-speed video and image processing techniques are used to extract experimental data.

Universal response of optimal granular damping devices [PDF]

, 2012
Granular damping devices constitute an emerging technology for the attenuation of vibrations based on the dissipative nature of particle collisions. We show that the performance of such devices is independent of the material properties of the particles ...

Seismic performance analysis of Kuala Lumpur air traffic control tower by friction damper [PDF]

, 2009
In structural earthquake engineering, different kinds of energy absorption devices were invented during last 30 years (Guan et al, 2004). And more than one-decade research has shown that, on account of the virtue of no power requirement, rapid response ...

SEMI-ACTIVE CONTROL OF FRICTION DAMPERS

Journal of Sound and Vibration, 1997
Semi-active control of friction dampers has been proposed to improve the energy dissipation characteristics of passive friction dampers and to broaden the areas of application in which they can successfully be used. In this paper, we propose control laws for friction dampers which maximize energy dissipation in an instantaneous sense by modulating the ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Study of linear friction damper consisting of tilt lever supported with leaf spring and cylindrical block

Nihon Kikai Gakkai ronbunshu, 2014
For passive vibration isolation systems, a friction damper has an advantage that large damping is achieved using a simple mechanism and it is easy to maintain. However, the ordinary friction damper of constant frictional force has performance limitations,

Nutation Damper System [PDF]

, 1983
The Nutation Damper System is a three function mechanism designed for the Galileo Spacecraft, a spin stabilized deep-space probe to Jupiter. By damping the movement of a large deployable science boom acting as an outboard pendulum, the nutation damper ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

Advanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
