Abstract: | Theoretical computation of the own frequency doesn`t take into account the damping effect of the mixed liquids, the effect of the axial toad, the elasticity of the bearings, etc. So, the real own frequency will be obtained through the correction of the theoretical own frequency by the aid of some correctional coefficients which depend on the influences of the effects of the factors which were previously shown. The paper is presenting theoretical and experimental views about k,, which introduces in theoretical formula of real own rotational speed, the influence of axial force. |
