Friction Damper Optimization: Simulation of Rainbow Tests [PDF]
Journal of Engineering for Gas Turbines and Power, 1999 Friction dampers have been used to reduce turbine blade vibration levels for a considerable period of time. However, optimal design of these dampers has been quite difficult due both to a lack of adequate theoretical predictions and to difficulties in conducting reliable experiments.

Enhancing Friction Pendulum Isolation Systems Using Passive and Semi-Active Dampers
Applied Sciences, 2020 Friction pendulum systems (FPSs) are a common solution for isolating civil engineering structures under ground movements. The result is a base-isolated structure in which the base exhibits low shear stiffness in such a way that the input energy of the ...

Design of a frictionless magnetorheological damper with a high dynamic force range
Advances in Mechanical Engineering, 2019 This article discusses an increase in dynamic force range in a spring–damper unit achieved by elimination of sealings’ friction. This friction is a part of damping force that cannot be controlled; therefore, it is undesirable in magnetorheological ...
