摘要
In the paper, by means of the variational principle in geometrical nonlinear statement, a problem on parametric vibrations of a laterally strengthened orthotropic cylindrical shell contacting with elastic medium and situated under external pressure is solved. The external medium action was taken into account by means of the Pasternak model. The curve separating the areas of stability and instability of parametric vibrations was constructed on the plane "load-frequency".
