Optimal Design Methodology of Maxwell–Coulomb Friction Damper
The optimal design methodology for a Maxwell–Coulomb friction damper is proposed to minimize the resonant vibration of dynamic structures. The simple Coulomb friction damper has the problem of zero or little damping effect of the vibration of the spring ...

A controlled friction damper for vehicle applications [PDF]
This paper examines the performance of a servo-driven dry-friction damper in a car suspension application; this device is a potential alternative to a traditional viscous damper. The friction damper is semi-active: damping is controlled without energy introduction into the system and hence the power required is much smaller than fully active systems ...

A Semi‐active piezoelectric friction damper
SummaryThis research investigates the development of a semi‐active piezoelectric friction damper for controlling the seismic response of large‐scale structures. The proposed device is made of Duplex steel and leads to high friction capacity, which can be developed either in passive or semi‐active modes.

Experimental performance evaluation of elastic friction damper
Earthquakes are natural disasters that can cause large-scale damage to humans and property. Many methods have been proposed to reduce the damage caused by earthquakes. These include dampers that are applied to structures to provide seismic reinforcement.

Characteristics of elastomers-friction damper [PDF]
The effect of the work of currently designed vibration dampers is the implication of the structural solution and the materials used for the cooperating elements. A desirable solution in the construction of machines would be a silencer with a constant, temperature-independent level of energy dissipation. An evaluation of the work of silencers preventing

Analytical Formulation of the Jacobian Matrix for Non-linear Calculation of the Forced Response of Turbine Blade Assemblies with Wedge Friction Dampers [PDF]
A fundamental issue in turbomachinery design is the dynamical stress assessment of turbine blades. In order to reduce stress peaks in the turbine blades at engine orders corresponding to blade natural frequencies, friction dampers are employed.
