FEATURES OF TORSIONAL OSCILLATIONS IN THE SHAFTING OF SHIPS WITH ELECTRIC PROPULSION

It has been found that when a propeller interacts with ice, significant torsional oscillations develop that cause repeated overloads in all the components of the propulsion system. When exposed to harmonic disturbing forces, the electric propulsion plants with which most modern icebreakers and ice rated ships are equipped have a considerable effect on the development of such torsional oscillations. A detailed analysis of this effect upon the torsional oscillations of the propeller shaft of an electrically propelled ship is presented.
