Description
  • This paper is concentrated on modelling of friction effects in bladed disk of steam turbine, which are realized by means of friction elements placed between blades shroud. The purpose of these elements is to decrease potential high vibrations of bladed disk due to requirement of wide frequency operation range and due to steam flow fluctuations. The model consist of 3D modelled disk and 1D modelled blades. The stiffness coupling matrix and the damping matrix of friction elements effects are obtained by forced vibration of bladed disk, relative movement of adjacent shroud contact areas and by centrifugal forces of friction element.
