Proposal of a Mechanism for a Rotational Friction Damper With Translational Movement and Hysteretic Characteristics

Year: 2024

Type: article

Abstract: This paper introduces a novel rotational friction damper with translational movement and elucidates its hysteretic characteristics. Experimental tests and finite element analyses were conducted to explore these characteristics. A key aspect of this damper is its unique behavior where the load increases with displacement, contrasting with conventional rotating friction dampers, which is attributed to the influence of translational movement. A hysteretic characteristic model based on the work principle was developed and demonstrated accurate estimation of the damper’s behavior. The proposed mechanism offers promising advancements in structural damping technology, with potential applications in seismic mitigation and structural resilience.
