U ovom radu prikazan je postupak merenja, kao i rezultati dobijeni merenjem nivoa torzionih oscilacija u sistemu prenosa snage sa brodskog dizel motora na propeler. Primenjen je princip merenja torzionog napona u funkciji broja obrtaja brodskog motora upotrebom savremene merne opreme. Proveren je položaj kritičnih brojeva obrtaja i nivo naprezanja propelerskih vratila, i na osnovu toga data ocena tehničkog stanja sistema sa aspekta naprezanja usled torzionih oscilacija. / The measuring treatment, as well as the results of torsional vibrations in the transfer from the ship diesel engine to the propeller are shown in this work. The measuring principle of torsional stress according to the function of rotation number of ship engine is applied by using of modern measurement equipment. The position of critical rotation numbers and the level of propeller shafts stress have been checked, and on the basis of these indices the evaluation of technical condition of the system has been estimated from the aspect of torsional vibrations strain.
