Multilayer structures are widely used in machine building, aircraft building and other industries. The article deals with the action of a moving load on a ribbed cylindrical shell. A technique and algorithm are being developed for determining the displacements and stresses of various points of shell structures. A solution to the problem of the action of moving loads on an infinitely long cylindrical shell, reinforced along the outer surface with longitudinal stiffeners and containing a viscoelastic inertial filler, is obtained. The moving load is transferred to the shell only through the ribs, there is no load outside the ribs. The discreteness of the location of the ribs is taken into account by writing the equations of motion of the A solution is obtained for the problem of the action of moving loads on an infinitely long cylindrical shell, reinforced along the outer surface with longitudinal stiffeners and The moving load is transferred to the shell only through the ribs, there is no load outside the ribs. The influence of the number and stiffness of ribs on the nature of the distribution of shell displacements and contact pressure at the filler boundary is shown. The movement of the shell is described by classical equations based on the Kirchhoff-Love hypothesis, for the filler, the dynamic equations of Lame’s theory of elasticity are used. On the basis of the results obtained, it was found that the contact stresses change sign very quickly with distance from the loading point and, in the case of one-way coupling, lead to lagging of the shell from the filler.
