ON THE PROBLEM OF RELATED TORSIONAL-LONGITUDINAL VIBRATIONS OF THE SHAFT DRIVE ENGINE WITH THRUST PROPELLER UNIT ON DIESEL SHIPS

It is proposed that longitudinal vibrations of propeller shafts are always accompanied to some extent by torsional vibrations. Analysis of the results of tests on the ship Pioneer show that resonant and near-resonant torsional vibrations of uninodal form are the sole cause of large vibrations of the main-engine thrust bearing. It is found that the zone of resonant torsional vibrations can be moved far beyond the speed range of the main engine by increasing the rigidity of the intermediate shaft, thereby preventing damage to the mounting bolts. The study of related torsional-longitudinal vibrations is of great value in increasing the reliability of ship power plants. When operation of the main engine is accompanied by torsional vibrations, the longitudinal pulses that excite them originate in the propeller and crankshaft.
