Вынужденные нелинейные колебания турбинных лопаток c динамическим контактом в разъемном бандаже при синфазном нагружении

Abstract

The work deals with studying of the vibrations of the steam turbine blades with detachable bandage shroud. The dynamic characteristics and their comparative analysis have been calculated for the developed linearized and non-linear finite element models of the two blades package. The results show the possibility of the opening in the split parts of the shroud during vibrations and their nonlinear nature
