Experimental and numerical investigation of friction element dissipative effects in blade shrouding
Original language description
The reduction of undesirable vibrations of turbine blades damped by the inserted friction elements in the shroud has been investigated. The interaction of the friction elements and blades was described by normal contact and tangential friction forces. Mathematical blade models were based on the finite element method. The dry friction forces were modeled by the modified Coulomb law. The numerical results showed the satisfactory agreement with the experiment.
