Abstract
The vibration system treaded in this study is of a single degree of freedom, and consists of four dampers and a mass. The viscoelastic material (VEM) for vibration control using the damper is urethane resin. The vibration transmissibility and loss factor of the resin are measured by forced vibration of the damping system. The transmissibility curve that were obtained experimentally have some influence on the excitation displacement amplitude. The loss factors are calculated by the maximum vibration transmissibility, and the effects of excitation displacement amplitude and static compressive stress on the loss factor are evident.
