| dc.description.abstract-translated | Self-excited flutter vibrations of turbine blades are very dangerous phenomena for the service life of turbines. The various design treatments are therefore applied for suppression of blades� flutter vibrations. The introduction of dry friction elements is one of the very effective methods. The dynamic behavior of a computational model of 30-blades turbine wheel is investigated in the proposed paper. The blades in the rotating cascade are excited by aerodynamic forces arising from the spatially periodical flow of steam through the stator blades cascade. This flow produces both forced vibration and self-excited vibrations - flutter. The application of dry friction elements on reduction of these dangerous vibrations is presented on several examples. | en |
