The viscoelastic damper is a kind of passive damping device and its energy dissipation characteristics are mainly influenced by temperature,frequency and strain amplitude. Firstly,this paper introduces the basic struc-ture and working mechanism of viscoelastic dampers. Secondly,we write a corresponding computer program accord-ing to the numerical calculation method of fractional derivative model,change the temperature,frequency and strain amplitude in the program respectively and calculate the storage stiffness,loss stiffness,loss coefficient according to the hysteretic curve. Finally,we discuss the effect of three kinds of related factors,which is used to evaluate the softening characteristics and the energy dissipation ability of the viscoelastic damper.
