One of the most important items for turbine reliability is the torsional vibration of the blade-disk-shaft system. In this paper, an effective method for calculating the torsional vibration of the blade-disk-shaft system is proposed by applying the substructure synthesis method. In this method, at first natural frequencies and mode shapes of blade-disk systems are calculated by the finite-element method, and then the torsional vibration of the blade-disk-shaft system is analyzed by the transfer matrix method using the calculated results of blade-disk systems. Because the actual turbine rotor includes many identical blade-disk systems, the torsional vibration of the whole system can be analyzed effectively using this method. In order to verify the validity of the analytical method proposed here, the results calculated using the substructure synthesis method are compared with the results calculated using the direct finite-element method. Also, a verification test is carried out and the experimental data are compared with the numerical results.
