摘要：
In the process of using cohesive element method to simulated ocean structure and sea ice, the effect of water is not considered, which is inconsistent with the practical application. Based on LS-DYNA finite element software, two different thicknesses of adhesive element ice models were constructed. By means of S-ALE fluid-solid coupling method, a numerical simulation of cylinder upright structure colliding with layer ice was carried out. The destruction mode of ice in the middle of the collision process and the ice load of the column were studied. The numerical simulation results coincided with the actual observations. Then the effect of mesh size on coupling effect and ice load is analyzed. The results showed that the ice load of the cylinder positively correlated with the flow field mesh. When the flow field mesh is twice the ice unit, the calculation time and coupling effect are optimal. © 2023 Chinese Vibration Engineering Society. All rights reserved.
