Study of characteristics of vibrations of mistuned bladed disks of turbomachines on the basis of reduced-order modeling by finite element method

This paper presents reduced order modeling (ROM) technique to investigate the influence of mistuning of bladed stiffness on characteristics vibrations of bladed discs of turbomachines by finite element method (FEM). Also the authors give the comparison of the results of ROM with experimental results and the results, which are obtained using FEM for the full model (FM) and using software ANSYS and some recommendations for characteristics vibrations of mistuned bladed discs of turbomachines.
