Proc. ASME. ESDA2010, ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 5, 347-355, July 12–14, 2010
Publisher: American Society of Mechanical Engineers
Paper No: ESDA2010-24948
..., accurate modelling of friction damping is mandatory. One of the most common sources of friction damping in turbine blades is the blade root, where energy is dissipated by friction due to microslip between the blade and the disk contact surfaces held in contact by the centrifugal force acting on the blade...

... Friction damping dynamics turbomachinery contact models Resonant vibrations affect fatigue life of vane segments. Friction damping is employed to reduce vibration amplitude. When vane segments are assembled, they are twisted so that lower platforms are in contact. The sum...
