Abstract
This paper investigates vibration suppression effect of novel Tuned Mass Damper, namely Wired Tuned Mass Damper (WTMD).WTMD is a tuned mass damper made of an auxiliary mass connected with two small masses with wires. The weights of the small weights give the main auxiliary mass restoring force, while the wires allow the main mass to move over longer stroke than ordinary springs allow. With displacement of WTMD, the restoring force increases and is replaced by nonlinear vibration from linear vibration. In this study, an experimental structure and WTMD is built, and vibration suppression property of WTMD is investigated experimentally. The WTMD showed satisfactory vibration suppression performance. Meanwhile, characteristics of restoring force depending on parameters are shown, while new experimental structure and WTMD is designed and developed. As result of this study, the vibration suppression performance was verified of WTMD that made. Alignment of WTMD can be adjusted by adjusting the tension of a wire by adjusting the ratio of tension to wire length; it checked that stability could be determined. Confirmed that operation of the restoring force was possible by the adjustment of the parameter. The equation of restoring force properties of the wire confirmed that operation of the restoring force was possible by the adjustment of the parameter.
