Sažetak
The paper presents improved methodology of ship hydroelasticity analysis, based on the modal superposition method and including structural, hydrostatic and hydrodynamic models. Structural beam model is used comprising a reliable advanced thin-walled girder theory taking into account shear influence on torsion as well as the contribution of bulkheads and the engine room structure, as structure discontinuities, to the ship hull stiffness. Consistent restoring stiffness is included in the analysis via hydrostatic model. Hydrodynamic loading and added mass and hydrodynamic damping are a part of the hydrodynamic model and are determined based on the radiation / diffraction theory. Also, the analysis of springing effect on the ship fatigue life is introduced using the combination of the improved hydroelastic model and 3D FEM substructure model. It is shown that the improved beam hydroelastic model can be efficiently used in the assessment of stress concentrations of ship structural details. Applicability of the developed theory is proved within global hydroelastic analysis of a 11400 TEU container ship as well as stress concentration determination in the selected structural detail.
