As a kind of passive control device, viscoelastic damper has been successfully applied to allkinds of engineering structures. However, the viscoelastic material in viscoelastic dampers is mainly basedon rubber. Therefore, in this thesis, the viscoelastic material is the main line of study. Different viscoelasticmaterial formulas are being used to make the corresponding damper and study the correlation performanceof such damper in the low frequency region. In this thesis, we mainly study the polyurethane elastomermaterial, but simplex polyurethane elastomer materials have low damping and cannot achieve the effect ofbuilding damping, so it's necessary to study the modification. In this experiment, four kinds of inorganicfillers, mica powder, zinc oxide, silica and glass fiber were used to modify the polyurethane elastomer. Itsdamping performance then is tested by a dynamic load testing machine in a low frequency region of 0.1Hz-1.0Hz.
