    Diagnosing elements of propulsion plant of naval vessels by means of vibration measurement
    (Wydawnictwa AGH, 2005) Charchalis, Adam; Ćwilewicz, Romuald; Grządziela, Andrzej
    The application of vibro-acoustic analysis methods in naval technology has been presented in the paper. This element of Base Diagnosing System (BDS) is accepted and used in the ships, which are powered by the COGAG power plant. The paper presents investigations of permissible in-service unbalance and appropriate assemblage of turbine rotors on the basis of selected vibroacoustic parameters, and finally determination of their permissible operation time resources. Another element of BDS is vibration control of misalignment of propulsion shafts. The described conception concerns evaluative process of the centring state in a transmission shafts within powered, marine gas turbine system as a function of ships displacement. Some structural components of the gas turbine unit and reduction gearbox have been selected for the analysis. Some results of the vibro-tests have been presented as well. All tests had been worked out during sea trials. This described idea is based on the researches of the corvettes' 1241 type power plants.
