Recently, in order to improve thermal efficiency, the thickness of the compressor blade and vane has become thinner. Therefore, for the purpose of increasing reliability, the vane with a friction damper has been used. This paper presents the analysis method to predict damping characteristics of the compressor vane with a friction damper by applying the substructure synthesis method and the harmonic balance method. The excitation test of the damper vane is carried out to verify the validity of the analysis method proposed here. ln the excitation test, the newly developed magnetic exciter, which applies the feature of the resonant circuit, is used to experiment the vane with a large excitation force. Numerical results show good agreement with the experimental data and the damping characteristics of the damper vane is clarified.
