Firstly the 3D FE solution and analysis of the imperfect blade disk dynamics is presented. Then the dry friction effect is studied analytically on linearized spring-dry-friction model consisting of equivalent linear stiffness and damping coefficients. An influence of nonlinearities and unproportional damping distribution on response curves is discussed as well.
