“…Articles [16][17][18][19][20][21] are devoted to studying the dynamics of structurally inhomogeneous, multi-connected shell structures, considering the influence of liquid and viscoelastic elements. Based on the laws of mechanics and the Lagrange principle, a mathematical model of the structure has been developed.…”

The paper presents the choice and method of calculating thin-walled structures that adequately reflect deformation in the compensator example. When choosing a design model, the influence of structural elements and their mechanical characteristics on its behavior in various operating conditions is taken into account since sometimes small changes in the design model can significantly impact the design analysis results. The complete design scheme of most designs, particularly the compensator, leads to statically indeterminate systems. Taking into account the energy dissipation in the shell material; the boundary value problems are reduced to a system of ordinary differential equations of the 12th order. The forms of natural oscillations for the first four natural frequencies are given. It is established that the inertia forces acting in the axial direction do not significantly affect the stress-strain state of shell structures.

“…In works [8,9,10,11], dynamic problems for the "structure-soil" system are considered. Nonlinear vibrations of an axisymmetric body under the action of impulse loads, forced axisymmetric vibrations of a viscoelastic cylindrical shell, natural vibrations of structurally inhomogeneous multiply connected shell structures with viscoelastic elements are considered [12,13,14]. The method of compensating loads applied to the problems of equilibrium, vibrations and stability of plates and membranes is presented in [15].…”

The longitudinal vibration of a cylindrical rod has been studied in an elastic medium from the action of axial harmonic forces in a state of compression tension. The consideration took into account the damping of vibration of the rod according to the theory of E.S. Sorokin. Taking into account, internal friction made it possible to approach the real state of the rod as a source of wave radiation. The amplitude-frequency characteristic of the structure is built, taking into account changes in the parameters of the environment and the rod. The possibilities of the emergence of the resonance state of the rod are established. At the same time, cases were considered with and without inelastic properties of the rod material. The analysis of the influence of the properties of the environment and the rod on the amplitude of the displacement of the latter is carried out.
