Study of the dynamic process in a nonlinear mathematical model of the transverse oscillations of a moving beam under perturbed boundary conditions

The study of transverse oscillations of systems moving along their axis is a very difficult, but at the same time a very important task.  Mathematical models of nonlinear transverse oscillations of a beam moving along its axis are analyzed in this paper work, both for non-resonant and resonant cases.  The task becomes even more complicated if we additionally take into account the method of fastening the ends of the beam or the perturbation at its ends.  We have obtained dependencies that can be used in construction, transport, industry, mechanical engineering and other
