Kiryuhin A. The perfection of functional properties of the shafts' holding and stabilizing systems of the ship turbine plants

The scientific-applied problem of increasing the effectiveness of the shipboard aggregates' shafts and shafting during the lifecycle of marine vehicles is solved by means of designing methodology of scientific research is worked out that concerns creation of the holding and stabilizing systems for the shafts of marine turbine power plants. The theory of axis holding and stabilization of the shafts oscillations is developed. Mechanisms are determined and effectiveness of the influence of adaptive and dissipative processes in the bearings' actuating medium on the exactness of axis holding and stabilization of shafts oscillations is determined. The method of imitative forecasting of the ship turbine plants shafts holding and stabilization system capacity is improved. Propositions on parametric optimization, nomination of failsafe modes and diagnosis of technical state of the systems for holding and stabilizing of the shipboard aggregates shafts and shafting are generalized and developed. The results of researches are applied in industry of the ship turbine plants, realized in the projects of power plants and in positions of operating documents for the Ukraine Navy ships.
