The assumed mode method and the singular integral equations with respect to the circulation density are used. The theoretical basis and mathematical models of the nonlinear vibrations of the thin-walled structures in gas stream are developed. Mathematical model of aeroelastisity accounts nonlinear properties of mechanical structure. Singular integral equations with respect to aerodynamic derivatives of the pressure drop are obtained at first. This allows to analyze bifurcations of the vibrations without accounting of the wake. The results of this research can be used on the industries of aerospace and power engineering Product Description popup.authors Аврамов Костянтин Віталійович Міхлін Юрій Володимирович Романенко Валентина Миколаївна popup.nrat_date 2020-04-02 Close
