Dynamic response analysis of imperfect bladed disk
Original language description
The paper presents a methodology for imperfect bladed disk vibration ananlysis of damped blades with friction elements applicable for the experimental investigation in Institute of Thermomechanics AS CR. The method is based on discretization of a disk and blades by FEM. The friction forces in contact areas of the friction elements are respected in the bladed disk model by iterative harmonic balance method. The excitation is considered by aerodynamic forces or by kinematic movement of rotor shaft. The results show the positive impact of frictional forces particularly for aerodynamic excitation.
