The INFLUENCE OF A FLY-WHEEL IN A ROTOR-BEARING SYSTEM ON ITS CRITICAL SPEEDS

Abstract

The paper highlights the influence of the presence of a fly-wheel on a rotor-bearing system in the removal of the critical speed in a rotational speed interval. The stiffness of the bearings and the damping introduced by them, the gyroscopic effect on the system elements are taken into account. The quantification of the dynamic influence of the fly-wheel is carried out with the help of Campbell diagrams in the finite element analysis program Ansys Workbench, taking into account gyroscopic effects.
