Two-dimensional linear friction damper consists of concave conical lever and disc (Investigation of fundamental property by simplified model)

Nihon Kikai Gakkai ronbunshu, 2015
A passive vibration isolation system consisting of a friction damper is advantageous at cost, a maintenance, etc. However, the conventional damper of constant friction force has performance limitations; the isolation performance declines and the residual

Earthquake response of adjacent structures with viscoelastic and friction dampers [PDF]

Theoretical and Applied Mechanics, 2015
We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base.

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 ...

Diagnostics of dissipative characteristics of friction damper

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The aim of our study was to broaden current knowledge of characteristics of friction damper that acts to dissipate the energy of small translational oscillations in friction pairs and to convert it into significant angular shaft movements. We have devised a novel methodology to evaluate elastic-dissipative characteristics of the
