In this paper, the probabilistic characteristics of the rotor system in the presence of random friction torque are studied. The influence of the small rotation speed on the maximum possible stress of the rotor is analyzed, and the simplified formula for the dynamic strength design of the rotor is derived. The results obtained for the development of special high-speed centrifuge has a guiding role.
