Essay

The thesis is devoted to developing methods of research of oscillating processes of two-dimensional axially-moving flexible elements. It is based on presentation of the process for linear analogues of systems in the form of imposition of direct and reflected waves with different lengths, but with the same frequency. For nonlinear models of systems, two-parameter set of solutions is received by using basic ideas of Van-der-Pol and averaging methods. It determines the influence of nonlinear and periodic forces on the oscillations. Resonant and non-resonant cases are considered. The impact analysis of the dynamic the process of voltage in the flexible elements is held.
