摘要：
The characteristic torsional oscillations of a hollow shaft with a longitudinal radial through cut are studied. It is shown that if the cut is positioned in the node of oscillations, the natural frequencies do not depend on the cut length. With increasing cut length, the basic frequencies of the characteristic torsional oscillations decrease. For a longitudinal through cut in a hollow shaft, changes in the characteristic torsional oscillations are considerable as compared with changes in similar frequencies in a shaft with a transverse notch. The original coordinate and the length of the longitudinal radial through cut in a hollow shaft are defined by two natural frequencies of the torsional oscillations.
