The real balancing machine consists of flexible rotor, oil-film bearings and bearing heads on the spring elements. The mathematical model enables to calculate of eigenvalues, critical revolutions and unbalance vibrations in dependence on the rotational speed. The identification method is based on a minimization of the differences between calculated and measured displacements of the nonrotating rigid bearing heads caused by attached known trial masses in the arbitrary rotor balancing planes.
