Energy Technologies & Resource Saving| Summary: | Thin-walled structures with geometrical nonlinearity flowing by potential gas stream are analyzed. The method for stability and bifurcations analysis of such systems is investigated. The basis of this approach is solution of the singular integral equations with respect to aerodynamic derivatives of the pressure drop. Using the Bubnov-Galerkin method, the nonlinear dynamical system with respect to the plate general coordinates is derived. The combination of the shooting technique and continuation method is used to analyze bifurcations and stability of the self-sustained vibrations. |
