Abstract


In the article, the stability of systems with finite of degrees of freedom is considered at the determined and stochastic action on the example of a suspension bridge. Calculations are executed on two models: the first one describes oscillations of a rigidity beam of the bridge by system of two partial differential equation and the second describes the same oscillations with help of FEM. Influence of parameters of the stochastic excitation on the value of the critical parameter is investigated.
