Abstract

An experimental study of a single-stage structure subjected to forced and free vibrations is presented in this article. The primary goals of the investigation are to identify the natural frequencies and analyse their dynamic behaviour. Homogeneous cantilever beams and their variations are tested using the DEWESOFTX software, both with and without a copper beam condition. An examination of free vibration was done. The structures were mounted on a modal shaker for forced vibration analysis, and the frequency response under forward sweep excitation was examined. The natural frequency was determined to be 7.324 Hz in the forced vibration scenario and 8.54 Hz in the free vibration case for the single-stage structure without a copper beam, showing good agreement. The natural frequency dropped to 7.42 Hz for free vibration and 7.32 Hz for forced vibration when a copper beam was added, indicating its potential as a tuned mass damper (TMD) to successfully lessen the vibrations. The structure’s amplitude has been successfully decreased, and its stability and performance have been improved by using a copper beam as a vibration-damping medium. Analysing the vibration and damping properties of copper as a tuned mass damper is the aim of this study. Finding a single-stage structure’s natural frequency under forced and free vibration settings with and without a copper beam as a TMD is the main goal of this work.
