Opis:: The paper presents identification of main errors which may occur during dynamic analysis of ship's hull and superstructure. The investigation was realized on the basis of calculations of natural and forced vibrations. The analysis was performed for cargo ships with typical propulsion system. Multi-variant computations of ship vibration were carried out with the use of previously identified excitation forces. A computation method for excited vibrations of ship hull and superstructure was developed.

Tytuł:: Forces exciting vibrations of ships hull and superstructure
Autorzy:: Murawski, L.
Powiązania:: https://bibliotekanauki.pl/articles/259533.pdf
Data publikacji:: 2005
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: hull vibration
superstructure vibration
main engine vibrations
excitation forces
pressure pulses
propulsion system's reactions
crankshaft-propeller phasing
Opis:: The paper presents identification of main excitation forces ofvibrations of ship hull and its superstructure, as well as investigation of influence of the analyzed excitation on ship vibration level. The following excitation forces were analyzed: dynamic pressure on the transom deck, propeller-generated hydrodynamic forces, as well as internal and external engine-generated forces. Rigidity and attenuation characteristics of lubricating oil film were taken into account in the analysis of the excitations transmitted by the propulsion system bearings (stern tube bearing, intermediate bearing, engine s main and thrust bearings). The dynamic characteristics of ship's power transmission system were also taken into account.Results of the analyzes were verified by comparing results of the computations and measurements.
