The article discusses methods of modelling reactions in systems of rotor-bearings-supporting structure type. Author's attention was focused most of all on modelling reactions between the supporting structure and the rotor supported on slide bearings. In the article an overview of well known and presently used methods for determining dynamic characteristics of the rotor supporting structure is given. Significant part of the article is devoted to the presentation and discussion of the proposed method of determining supporting structure characteristics in cases when subtle changes of these characteristics, for instance those caused by the presence of certain defects, are to be taken into account. The proposed method of dynamic characteristics determination allows various changes taking place in the structures supporting the rotating machines to be analysed both at the design stage and during their operation. These changes have frequently noticeable influence on the rotor dynamics.
