Friction dampers, the positive side of friction
2004Friction is frequently seen as an unwanted phenomenon whose influence has to be either minimised or controlled. In this work one of the positive sides of friction is investigated: friction damping. Friction dampers can be a cheap and efficient way to reduce the vibration levels of a wide range of mechanical systems.

Dynamics of a Power Collector With Friction Dampers
Journal of Engineering for Industry, 1976Using the friction damper, the construction of power collector for a very high-speed railway will be considerably simplified. In this paper, the power collector with friction dampers is considered, and its dynamic characteristics are analyzed by the equivalent linearization technique.

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.

Torsional vibration damper for a friction clutch
The Journal of the Acoustical Society of America, 1982A torsional vibration damper has an input hub and an output hub drivingly connected by a plurality of elastomeric band support members and an elastomeric band. The support members are maintained in contact with at least one of the hubs by the elastomeric band.

Characterization of Turbine Blade Friction Dampers
Volume 6: Turbo Expo 2004, 2004This paper discusses approach for characterizing the dynamic behavior of a friction damper. To accomplish this, the deflection of the damper is measured as a function of an applied force for a range of amplitudes, normal loads, and excitation frequencies.

Dynamic models of friction wedge dampers
Proceedings of the 1997 IEEE/ASME Joint Railroad Conference, 2002Friction wedges play a central role in the vertical dynamics of railroad freight cars. They also play a role in lateral dynamics and stability. While friction wedges are mechanically very simple, their inherent nonlinearities lead to complications in modeling and dynamics.

Friction Dampers to Control Building Motionics
Architectural Science Review, 2000Means of dissipating energy in buildings oscillating due to seismic activity include viscous dampers, yielding of the structural members or of added sacrificial elements, and friction devices which slip when ground accelerations exceed a specified value. Of these schemes, friction dampers have proved to be the cheapest and least intrusive, and the most

Cable damping with friction and combined viscous-friction dampers
2009This paper investigates the optimal tuning of friction and combined viscous-friction dampers located at 2% cable length. The optimality criterion is maximum cable damping. The force of the friction part is adjusted in proportion to the damper displacement amplitude in order to avoid cable clamping and generate almost amplitude independent damping.
