In the meantime, the difference between a direct integration method and a modality superposition method in the nonlinear solution of large sized shaftings was also investigated. It can be shown that the use of a nonlinear method for solving the kinetics response of a higher dimensional rotor bearing system is both essential and feasible. With regard to the nonlinear kinetics problems of a rotor system the direct integration method is more effective than the modality superposition method. steam turbine, rotor, dynamics, nonlinearity
