AnnotationUsing the Kantorovich-Galerkin method, an approximate solution of the problem of transverse vibrations of a viscoelastic rope with a moving boundary lying on an elastic base is found. The dependence of the drag force on the movement of the rope is assumed to be proportional to its speed. The flexural rigidity of the rope is taken into account. The results obtained for the amplitude of the oscillations corresponding to the n-th dynamical mode are presented. The phenomenon of steady resonance and passage through resonance is investigated. The solution is obtained for the most common case in practice, when external perturbations act on a moving boundary.
