КОЛИВАННЯ І СТІЙКІСТЬ КРУГЛИХ ПЛАСТИН З ПРОМІЖНИМИ ОПОРАМИ

Abstract

The highest frequencies and vibrations of symmetrical fluctuation of a circular plate with a dot central support for a jamming, hingesupport with a sliding jamming of edge were determined. The frequencies of symmetrical vibrations and the magnitude of the critical compressive stresses for a plate with an elastic jamming of edge relatively a turn and with an intermediate circular support were determined Frequency of symmetrical oscillation of circular plate in the case elastic fixing its external bearing were calculated for different variants of intermediate support (ξ = 0.1,0.2 ... 0.8). The coefficient of hardness relative to the rotation of the external bearing varies in a wide range (δ = 0-5000). In the same range of parameters ξ, δ are defined the critical stresses compressed and symmetrically deformable circular plates.
