Complex rotary systems (CRS) are widely used in energetic, chemical industry. Their reliability is one of the main tasks of plant engineering, because costs of maintenance and production loses are really significant.
Vibrodiagnostics of such systems is one of the main tools applied for the evaluation of machines condition. However complexity of those systems, probability of various defects condition that reliable determination of sources of vibrations is not always achievable. Therefore additional mean for defects determination may be applied - numerical modelling of systems dynamical condition.
This article presents data of experimental and numerical research of a CRS, where the phenomenon of rubbing occurs and subharmonic vibrations are generated. Modelling of such realistic system is also a highly complicated problem, therefore improvement of numerical model, based on experimental data is needed.
