Study on the Structural Strengthening Design under the Ship-ice Collision Load.

In order to investigate the water media effect on Structure response under ship-ice collision load. This paper presents a study on ship-ice collision considering the effect of water media for the first time. The ship-ice collision is simulated in aqueous medium and the coupling behaviors between the ship, water and ice was considered. The calculation model is applied to various working conditions of ship-ice collision calculation. The parametric study on the thickness of shell and transverse diaphragm and the spacing of the frames is then conducted. The damage deformations, collision forces, structural energy absorptions varying with thickness of shell plate, thickness of the transverse diaphragm and different spacing of frame are discussed. The capability and contribution of each major component in the shoulder of the ship on the resistance of ice loads is analyzed. The conclusions are of great significance in improving anti-ice load ability of ship structure. [ABSTRACT FROM AUTHOR]
