The Purpose of the Study is to study the relationship between frequency and wave number using the equation of torsional vibrations, in particular, in the interaction of a two-layer viscoelastic shell with the outer layer of the viscoelastic body and the inner layer of the viscoelastic body, which is elastic. The Research Methodology. To study the problem and formulate conclusions, methods of analysis, description and synthesis of data were used. The Scientific Novelty. A mathematical model of physical nonlinear torsional oscillations of circular conical shell and stern was developed taking into account the physical nonlinear relations of H. Kauder. The Conclusion. As equations of torsional vibrations of a two-layer cylindrical shell, the equations derived by the authors in their previous works for the viscoelastic case were obtained, from which frequency equations were obtained for the case when the surface of the shell is under stress -free, and they were solved using the Maple 17 program. The graphs were analyzed for cases with different materials and thicknesses of the edge and middle layers.
