In this paper, the transfer matrix impedance coupling method for calculating the eigensolutions of multi-spool rotor systems with several intershaft bearings is developed. This method can also be used for the eigensolutions of the damped rotor systems. The numerical examples of dual and tri-spool rotor systems with intershaft bearings show that the results are in good agreement with the exact solutions.
