Abstract
The influence of the rotating rotor on the free vibration frequencies of the damped mechanism is considered. Under the assumption of absolute rigidity of both the body of the mechanism and its rotor, a system of differential equations for determining the free oscillation frequencies is obtained. The analysis of this system shows that the spectrum of natural frequencies is determined not only by the static characteristics of the mechanism (mass and moments of inertia) and its depreciation, but also by the speed of rotation of the rotor.
