The main feature of the specified effect is the absence of frequency multiplicity of the non-accelerated rotor natural oscillations. The situation takes place when dynamics of the available rotor elastic support is also taken into account. The article considers this effect simulated by the elementary gyroscopic system, the results of the laboratory resonance tests are presented as well as the results of modeling the kinematic excitation of the beam-supported rotor using the MSC.Nastran.Rotordynamics software.
