The consideration of damping in structural dynamics problems is an important and non-trivial problem. Its complexity, not least, is due to the need to set the correct data for the materials used and to select a model suitable for analysis. In this paper, we consider some models of viscoelastic materials from the point of view of the possibilities of using these models for the harmonic analysis of the damping properties of various materials in the linear region of elastic deformations. The proposed analysis is based on the use of parameters of viscoelastic materials specified in the form of coefficients of the differential equation of small forced vibrations. It is shown that the considered models are characterized by a different frequency dependence of the parameters of the simulated materials. This opens up the possibility of combining the model with the frequency characteristics of its parameters, approaching the frequency characteristics of the parameters of the studied viscoelastic materials.
