摘要

Numerical simulation of an icebreaker advancing in level ice is carried out by using the nonlinear finite element method. An ice material model is verified by comparing the simulation results with experimental data. Using the ice material model, the dynamic response of the ship during icebreaking in level ice of different thicknesses at different speeds is numerically studied. The deformations of level ice, the magnitudes of ice force, the changes of ice deformation energy and kinetic energy during the icebreaking process are presented, and the influences of the ship speed and level ice thickness on the icebreaking resistance are analyzed. The results have a certain reference value for analyzing the dynamic response of an icebreaker in level ice.
