Numerical simulation of oscillations of a nonlinear mechanical system with a spring-loaded viscous friction damper [PDF]
MATEC Web of Conferences, 2019 The dynamics of a mechanical system consisting of a parallel-connected main elastic element, an external disturbance compensator having a nonlinear force characteristic, and a viscous friction damper sprung by a linear spring are studied.

Effects of Diagonal Friction Dampers on Behavior of a Building
Applied Sciences, 2023 In this study, the effect of the friction damper location on the earthquake behavior of a building was investigated. Diagonal braced friction dampers were placed on different floors, and the changes in building behavior were examined. For this purpose, a

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.

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

A controlled friction damper for vehicle applications [PDF]
Control Engineering Practice, 2004 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 ...

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
