Sažetak
The paper describes a coupled torsional-bending vibration model of a ship's propulsion shaft system with a residual shaft bow. The developed model presents an extension of the Jeffcott rotor model. In order to test the numerical model and determine the coupled torsional-bending vibrations, several cases were analyzed. First, a reference case corresponding to a fully axisymmetric ship propulsion system is set up. Then a shaft bow was introduced, and the influence of the constant radial force in the vertical direction at the position of the stern bearing was analyzed. Such conditions exist when a ship navigates on a calm sea under a partial or fully loaded hull. Finally, the case of sailing on a rough sea is analyzed when the propeller racing occurs due to the stern lifting out of the sea. Based on the results of numerical analysis, it was found that the proposed model well describes the coupling of torsional and bending vibrations of the propulsion shaft system with residual shaft bow. The aim of the research is to prepare input data for estimating the fatigue life of the propulsion shafting system of ships sailing at slow steaming speed for low carbon shipping.
