Local optimization analysis of bow structure of large polar container ships
In order to study the optimization scheme of the bow structure of the container ship,according to the ship sailing in a polar region,it is accurately modeled one-to-one in the finite element software,and the constituent layer ice mod-el that meets the homogenization elastoplastic is constructed,and the numerical simulation is carried out with the finite ele-ment model of the ship,the bow deformation and structural energy absorption changes in the collision process are studied,and then the results are compared and analyzed under different working conditions to study the influence of ship ice colli-sion on the bow under different optimized structures.The results show that the force and deformation size of the bow with the sleeve after optimization are much reduced compared with the original bow,and the sleeve absorbs part of the energy after the collision,so that the force generated in the collision area is borne by the covering,and the layer ice is broken,so that the hull part behind collides with the crushed ice,the force on the bow becomes smaller,and the damage and deformation are smaller.Studies have found that the thicker the sleeve and the more internal structure absorbs more energy,the better the pro-tection of the bow.
