Imposed rubber elements for bladed wheel vibration suppression
Original language description
The proposed contribution deals with a novelty research of a bladed wheel vibration suppression by inserted elements of temperature resistive rubber like materials. The FKM rubber was selected as a perspective material since it is known by its resistances against high temperatures and against aggressive chemicals. As a study case the five-blade bundle linked by wedge-form rubber elements imposed in the head interspaces of the neighboring blades was chosen. Thermo-mechanical effect on the dynamics of thebundle was investigated numerically and experimentally and a good agreement was achieved in modal characteristics of both approaches. The results of the study show that although the damping markedly decreases in high temperature 150^0 C with respect toa room temperature, the damping capacity of the FKM elements remains still relatively high with comparison to the interblade structural damping by means of the dry friction.
