Sažetak
Vertical and torsional ship structure vibration analyses for ballast and semi-full (design draught) loading conditions are performed by the finite element method. 3D model is used for the ship afterbody and 1D for the remaining part of the ship hull. For the space model the shell finite elements are used and for 1D model general beam elements. The hull stiffness and mass distribution are taken from 1D analysis. For the vertical and torsional vibration analysis the same FEM model is used with appropriate boundary conditions. Natural and forced vibrations caused by propeller and engine excitations are analysed and evaluated by ISO/DP 6954:2000 standards. Both supported and unsupported engine cases are considered.
