Description of the workflow in the linear magneto-electric drive at steady-state oscillations of prototypes elastomers due to the construction of mathematical models of individual subsystems of the drive, the union of these models in a general mathematical model for the entire drive, and the decision of the resulting system of equations with the equations of the relationship between design values and initial conditions and restrictions . The article describes an example of solving the problem on the dynamic characteristics of the magneto drive to test the viscoelastic properties of elastomers. To study the dynamics performed mathematical modeling of the individual subsystems of the drive. In drawing up a mathematical model that takes into account the viscoelastic properties of the elastomer used a prototype-based approach to the application of multi-loop equivalent circuit parameters are determined from experimental data obtained in the process of relaxation of stress at a given strain. The calculation of the stress, strain, voltage, power supply, mechanical and electromagnetic forces, as well as the results of the decomposition of deformation in a Fourier series with the release of the fundamental frequency of 10 Hz.
