In paper we investigated the influence of geometry imperfections on coupled flexural-torsional vibrations in the transient states, at start-up, in rotating systems. Consideration was given to two types of errors: the permanent deflection of a shaft in place of rotors installation (shaft bow) and inclination of a rotor plane with respect to the designed axis of rotation of the machine (angular misalignment). Used was the specialist Simulink library developed by the authors.
