Modeling and experimental investigation of a novel arc-surfaced frictional damper

In this investigation, an innovative type of frictional damper called Arc-surfaced Frictional Damper (AFD) is introduced. The damping force of such damper is secured by pre-compression of Polyurethane Elastomer (PUE). The major advantage of AFD is that its frictional surfaces are curved so that the damping force varies with displacement.
