The rubbing, as an undesired non-linear dynamical behavior of rotors, is a widely studied topic in the field of rotor-dynamics. Standard models usually use the classic Jeffcott rotor system with several rolling and journal (bearings without rolling elements, usually filled with oil) bearings, or with magnetic ones. The present paper investigates a model that takes into consideration also the gyroscopic effect and its influence on the rubbing phenomenon. © 2010 Akadémiai Kiadó.
