Abstract
As a result of global warming, the coverage and the thickness of sea ice in the Polar Regions is gradually decreasing, making energy development and maritime transport possible in the Polar Regions. However, ships will inevitably encounter the problem of collision between ships and sea ice when sail in the Polar Regions. In some extreme cases, the impact of sea ice on the ship can lead to catastrophic damage. Therefore, it is of great significance to study the influence of ship speed, collision angle and ice thickness on the response of sea ice collision structure. This paper uses the finite element method of the numerical method to study the ship-ice collision. The finite element simulation model was established by software LS-DYNA. The appropriate material model and material parameters were selected for the ship and sea ice to simulate the collision process of the ship and sea ice. In this way, the influence of ship speed, collision angle and sea ice thickness on the response of ship ice collision structure is obtained. This is of great significance to study the mechanism of ship-ice collision.
