The influence of journal’s static and dynamic angular misalignment on the synchronous unbalance response and linear stability threshold of statically indeterminate rotors is analysed. Both short and finite bearing models are considered in order to calculate hydrodynamic reactions, and rotating parts are modeled using beam finite elements. The results provide descriptions of the effects of the consideration of the 32 coefficient bearing model on linear vibrations analyses, together with guidelines for early design stage identification of rotor systems sensitive to angular misalignments.
