The characteristic of the viscoelastic damper and four calculating models which are used to analyze the viscoelastic damper are introduced. A new model-the equivalent standard solid model which can embody the effects of temperature and frequency is proposed, then through the analysis for two different materials, some conclusions are given out.
Keywords: viscoelastic damper; calculating model; equivalent standard solid model
