This article contains the results of studies of the rotation unevenness parameters of the ship power plants elements drive. Theoretical prerequisites of such analysis are described and an example of calculation of parameters of torsional-oscillating system of high-pressure fuel pump drive and speed controller is given in the article. Calculations have shown that at the nominal crankshaft speed of the internal combustion engine, the possibility of resonant oscillations of the camshaft of the fuel pump is not excluded. Design features, faults, violation of adjustments or operating rules can contribute to the operation of elements of power plants at resonant frequencies and cause operational failures. Analysis of rotation unevenness of elements drive and additional equipment of ship's power plants is an appropriate technical measure that allows to increase the reliability of ship's power plants.
