FORCED VIBRATION OF BLADED DISK
Abstract eng: The paper presents the modal synthesis method for a mathematical modelling of rotating bladed disk vibration. The standard finite element software does not allow to consider all effects of the rotation. The presented method makes it possible to respect Coriolis and centrifugal forces acting continuously on the threedimensional elastic disk and one-dimensional elastic blades connected together at the top with shrouds. A centrifugal blade stiffening is considered. The method is applied to the steady forced vibration of the real rotating bladed disk excited by aerodynamic forces.
