Abstract
A dynamic vibration absorber with a viscoelastic element is studied. The viscoelastic element is modeled as a material with memory in which the internal dissipative force depends on current, as well as previous deformations. The viscoelastic behavior is governed by two parameters: the relaxation modulus G0, and the relaxation time y. We apply the principle of time-temperature superposition to affect a dependence of the relaxation time γ on temperature. This temperature dependence can be used to tune a vibration absorber so as to be effective at more than one excitation frequency.
