A Novel Hull Girder Design Methodology for Prediction of the Longitudinal Structural Strength of Ships

Year: 2024

Type: article

Abstract: Ship hull girder model has been widely adopted in ship mechanics researches such as the small-scale and large-scale hydroelastic ship model experiments. This research proposes a simple and novel ship hull girder design methodology that overcomes some of the main shortcomings of existing methods. The main novelties of this research are (1) the structural rigidity design requirement for the ship hull girder corresponding to any targeted real ship with arbitrary structural complexity is precisely satisfied; (2) the mass density per unit length of the proposed hull girder is exactly only related to the mass density distribution of the targeted ship structures, and thus (3) a better ship hull girder model for prediction of the total structural responses can be consequently established. A real ship is adopted as the design target, the structural responses of the real ship and the proposed ship hull girder model are compared and analyzed. The proposed model is compared to the currently widely accepted ship hull girder models through numerical experiments. The proposed hull girder design methodology possesses potential of upgrading the classical structural design approach to match the growing trend of adopting finite element method(FEM) based approaches for ship structure researches.
