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 ...

The effect of friction in coulombian damper
IOP Conference Series: Materials Science and Engineering, 2017 The study aimed to analyze the damping phenomenon in a system with variable friction, Stribeck type. Shock absorbers with limit and dry friction, is called coulombian shock-absorbers. The physical damping vibration phenomenon, in equipment, is based on friction between the cushioning gasket and the output regulator of the shock-absorber.
