Essay

A method for analyzing the dynamic stability of elastic systems was elaborated for a large class of correlated and stochastic influences. A numerical method of studying the stability of parametrical vibrations under stochastic loads was elaborated. The proposed method was realized as an applied software for PC, which allows us to execute all the steps for constructing zones of parametrical vibrations' dynamical stability of a beam, a plate, a cylindrical shell under stochastic influence. That was proved that obtained results, for the systems under stochastic loads with a finite correlation radius, make significantly more precise the ones got by other authors earlier.
