Abstract
For a reduction of blade vibration amplitudes in airborne gas turbines special damper devices are used which usually are arranged between the blade platforms of neigboring blades. These dampers possess a cross section like a parabola or a circle and are formed out of sheet steel. The dampers are arranged between the platforms of the blades in such a way that they are pressed by centrifugal forces against the oblique plane, which will vibrate together with the blades. This motion causes some relative movement between damper and oblique plane thus generating dissipation by Coulomb friction. The design goal for dampers of that kind consists of maximizing dissipation which requires relative motion or, to put it another way, to minimize stiction time [47], [117], [116], [43].
