This paper deals with a new and simple method of optimum design of dynamic vibration absorbers which consist of viscoelastic springs and auxiliary masses. If the usual method of design of dynamic absorbers is applied to an absorber with a viscoelastic spring, the stiffness and the loss factor of the spring are determined as optimum values corresponding to the given ratio of the auxiliary mass to the principal mass. The actual value of the loss factor, however, cannot be chosen arbitrarily, because it depends on the material of the visco-elastic spring. In the proposed method, the optimum condition can be found for any combination of values of the mass ratio and the loss factor of the viscoelastic spring. Therefore, dynamic absorbers can be realized for springs of arbitrary viscoelastic materials.
