Usage of disk modal condensation to modelling of bladed disk vibrations with friction elements
Original language description
The paper presents the method of the mathematical modelling of rotating bladed disk vibrations with friction elements. A modelling is based on bladed disk decomposition into a three-dimensional elastic disk subsystem and a blading subsystem. Modal condensation applied to disk enables reduction of DOF number of the whole system. The influence of different condensation levels on eigenfrequencies and natural modes of the imperfect experimental bladed disk with friction elements placed between shroud in theend of several symmetrically arranged blades is discussed.
