In the paper coupled parametric vibration analysis of the three-bearing double span rotor-shaft system with two bladed disks has been performed by means of the analytical-numerical approach based on the discrete-continuous mechanical model. There were investigated rotor-shaft lateral vibrations coupled with its torsional-axial vibrations by the local shaft anisotropy co-operating with a bearing misalignment. For various rotational speeds a severity of the coupling effects between the mentioned kinds of vibrations was studied for several values of the bearing misalignment.
