The object of the research is an elastic-supported rotor of a servomechanism engine. The subject of the research is cross-effects of transversal and rotative  vibrations which take place at servomechanism rotor functioning. The goal of research is to investigate the cross-effects of transversal and rotative vibrations and to design a mathematical model regarding these cross-effects. Materials ant methods. The authors investigated the interrelation of transversal and rotative vibrations taking place during servomechanism rotor functioning. Results. The researchers have developed a linearized mathematical model of an elastic-supported rotor, which considers the interference of transversal and rotative vibrations. The work proves that transversal vibrations cause torsional deformations and visa versa. Conclusions. The research of rotor vibrations allows to conclude that the crosseffects of transversal and rotative vibrations are significant. It led to elaboration of the linearized mathematical model that takes into account this interaction.
