The test programme and the methodology of analyzing the vibrations spectrum of a Proteus 52M/558 ship gas turbine

The paper presents a programme for testing vibrations on a ship gas turbine, based on an analogy of testing and analysis of vibrations on aircraft and/or helicopter gas turbines. A particular attention is given to a choice of vibration parameters and to the analysis of the vibration spectrum as well as to the methods of estimation of criteria of vibration acceptability. The results of the measurement of the vibrations on a Proteus 52M/558 gas turbine installed on a RTOP-405 ship are shown. .
