Abstract: The stability of a multi-span rotor-journal bearing test rig is studied to find the influence of bearing misalignment on the system’s damping, the related parameters are identified by Prony method, dynamical behaviour of the system in instable region is discussed from the nonlinear system dynamics points of view.
