Self-Centering Frictional Damper (SCFD)
Engineering Structures, 2019Abstract This paper describes the behavior and design of a new self-centering frictional damper. This device is based on conic friction surfaces that lead to a flag-shaped hysteretic behavior. Its self-centering property and different possible configurations make it a very versatile device to be used in seismic applications of high-rise buildings ...

Parametric study on seismic response of the knee braced frame with friction damper
, 2021The present study deals with a new system based on the combination of knee bracing frame and friction damper (KBFD). The friction damper used in the present study was constructed as a linear friction damper with long slotted holes.

Drill rod Coulomb friction damper.
The Journal of the Acoustical Society of America, 2010The acoustical performance of a case-hardened Coulomb friction damper consisting of a case-hardened roll-threaded collar resting against a reverse taper segment of drill rod is discussed. Because of the axial impact, many transverse bending modes of vibration are excited in long prismatic drill rod, along with longitudinal and torsional resonances. The

Assessment of semi-active friction dampers
Mechanical Systems and Signal Processing, 2017Abstract The use of friction dampers has been widely proposed for a variety of mechanical systems for which applying viscoelastic materials, fluid based dampers or other viscous dampers is impossible. An important example is the application of friction dampers in aircraft engines to reduce the blades’ vibration amplitudes.

Semi-active control of friction dampers
Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002Quite a few papers have appeared dealing with how to minimize the effects of friction in machines. A recurring theme has been that friction is a dynamic phenomenon. As such, much attention has been paid to obtaining the appropriate friction model structure, and to the identification of model parameters.

Feasibility Research on Coupled Friction/Piezoelectric Dampers
Volume 1: Development and Characterization of Multifunctional Materials; Modeling, Simulation, and Control of Adaptive Systems; Integrated System Design and Implementation, 2018A new passive damper coupling the energy dissipative mechanisms of dry friction and piezoelectric shunting circuit is proposed. The idea is to embed the shunted piezoelectric materials to the dry friction dampers at appropriate positions, so that the elastic deformation of the dry friction dampers can be utilized to generate additional damping ...
