Abstract
The determination of natural frequencies and the mode shapes of vibration of discrete and continuous systems is one of the basic tasks that are solved in the vibrations of these systems. By knowing these values, it is possible to avoid unwanted occurrences in the system. In this paper the torsional vibrations of the shafts of a marine engine connected with a propeller through pair of gears are analysed. A well-known process of transforming gear system with a multiple shafts to a single shaft or torsion chain with definite number of degrees of freedom has been carried out. From this analysis natural frequencies and mode shapes of vibration have been obtained. Then, a numerical analysis of the torsional vibration of the shafts of the engine connected with propeller through a pair of gears has been carried out using the ANSYS software.
