Теоретическое исследование динамической устойчивости цилиндрических тонкостенных оболочек в процессе их вращения при наличии сжимающей нагрузки (нелинейное приближение)

Abstract

It is shown that the unlinearance exerts essential influence on the character oscillations of cylindrical casings in the process their rotation and the availability of compressible loading. The dependences, between the amplitude and phase static oscillations of casing from the frequency of external force were found by means of solution Duffinge s equations for the forced oscillations calculating the additional dicrease of oscillations on account of damping. The analysis of ampli­tude-frequency characteristics of process oscillation revolving casing is performed. The conditions stability static regimes of casing in the process its rotation under the availability of compressible loading and the damping are determined.
