Influence of Physical Parameters of Elastic Rotor on Asymmetric Supports on Frequencies Its Free Oscillations

The problem of finding frequencies of vibrations of the elastic rotor on asymmetric supports is considered. Taking into account the small free vibrations of the rotor, the frequency equation of the direct problem is obtained. According to the equation, the influence on the vibration frequencies of the physical parameters of the rotor and its elastic supports was investigated. It is shown that the increase in the stiffness coefficients of the supports leads to an increase in frequencies, and the increase in the mass of the rotor, on the contrary, to a decrease in the frequencies of its vibrations. Numerical calculations are given with the corresponding results in the form of tables and graphs of dependencies.
