Abstract

In the paper, a problem on parametric vibration of a stiffened cross system of ribs cylindrical shell contacting with external viscoelastic medium and situated under the action of internal pressure is solved in a geometric nonlinear statement by means of the variation principle. Influences of environment have been taken into account by means of the Pasternak model. Dependencies of dynamic stability area on parameters of the construction on the on "loadfrequency" plane are reduced and respresented on the form of a curve.
Keywords
