Research Experiences for Undergraduates (REU), NHERI 2023: Characterization and Modeling of a Semi-active Rotary Friction Damper

This project characterizes and further models the dynamics of a novel semi-active rotary friction damper. The presented work may serve as a baseline for achieving semi-active control of the analyzed damper. This project is unique in that it is the first to describe semi-active operating characteristics of a previously introduced device. The audience of this work is the natural hazards engineering community and those studying semi-active friction dampers.

本项目旨在表征并进一步建模新型半主动旋转摩擦阻尼器的动力学特性。所呈现的研究成果可为该阻尼器的半主动控制实现提供基准。本项目的独特之处在于，它首次描述了此前提出的一款装置的半主动工作特性。本研究的受众为自然灾害工程领域的研究者以及从事半主动摩擦阻尼器研究的相关人员。
