Abstract

By using the nonlinear finite element method to establish the 3D finite element models of ship and level ice, a numerical simulation of collision between ship and level ice is carried out. The ship’s dynamic structure response during collision with level ice of different thicknesses at different speeds is studied, and the magnitude of ice force, deformation of bow structure, changes of ship kinetic energy and deformation energy are analyzed. The influences of the initial ship speed and level ice thickness on the impact load of ship-level ice collision are illustrated. The results have a certain reference value for analyzing the ship structure performance during collision with level ice.
