abstract
It consists of four phases.
First phase, modal analysis is performed to determine the modal parameters of Turbine blade.
Second phase, a mathematical for the model for the contact region of damper and rigid surface is developed using micro slip approach.
In the third phase, a mathematical model for the combined blade with damper is developed.
In the fourth phase the damper is designed. The results of the combined blade with damper model are confirmed by experimental test.
