Multiparameter Optimization Design of Self-centering Friction Damper Using Shape Memory Alloy Bars
Journal of earthquake engineering, 2022In this study, the superelasticity of shape memory alloy (SMA) bars was used to develop a new self-centering friction damper (SCFD). A modified SMA constitutive model was established and verified using cyclic tensile test results of the SMA bars to ...

Experimental and numerical study of mortise-tenon joints reinforced with innovative friction damper
, 2021A new friction damper is proposed for improving the cyclic response of mortise-tenon joints at multiple levels of seismic motion. In order to investigate the combined behavior of the proposed damper, quasi-static cyclic tests are conducted on five ...

Torsional friction damper optimization
Journal of Sound and Vibration, 2006A new approach for the analysis of friction dampers is presented in this work. The exact form of the steady-state solution for a friction damper implemented on a primary system is developed and numerical solutions are used to determine the optimum friction in a friction damper applied to a specific primary system.

Friction braking type vibration damper
The Journal of the Acoustical Society of America, 1986A vibration snubber for earthquake protection of piping including an auxiliary cylinder axially slidable in a main cylinder having a large diameter portion. The large diameter portion houses a flywheel which is secured to a rotatable center shaft. One end of the shaft is mounted in a bearing in the cylinder end.
