Abstract

The paper presents the results of modeling the dynamic characteristics of the shaft of a laboratory centrifuge, which were compared with the results obtained analytically and experimentally. The obtained results showed the convergence of analytical and experimental data, in turn, the results obtained with the help of the KISSsoft software complex have overestimated values. The paper also provides determination of natural frequencies and forms of oscillations by the methods of the vibration theory.
