Condensation of bladed disk
Original language description
The aim of the paper is condensation of a system which represents bladed disk. These kinds of systems are mainly used in steam turbines where our interests are aimed. The model of the bladed disk is based on decomposition into a disk subsystem and a blading subsystem. The nite element method is used for modeling of the both subsystems. All inuences of steady-state rotation are respected as centrifugal forces, gyroscopic e_ects, centrifugal sti_ening of blades and dynamic softening. Blades are modeled byusing 1D elements and the disk is modeled by using 3D hexahedral elements. Modal condensation is applied to a sub-model of the disk. Di_erent levels of the condensation are presented and compared on a testing bladed disk.
