ABSTRACT
The objective of this study is to numerically investigate the influence of shape parameters of floating ice on the structural response of ship collision with floating ice. A 15000 DWT vessel was selected as analysis object by using the penalty function method and ALE fluid-solid coupling theory. A set of 5×5 models of floating ice were provided by varying the corner angle and the slope angle based on the principle of constant volume (mass). On this basis, numerical analysis were performed and three indexes of the collision force, maximum structural deformation and impact energy were employed to analyze the influence of floating ice shape parameters on structural responses. The result shows that the slope angle is the main factor affecting the structure response, and the influence of the corner angle is more reflected in the maximum deformation. The response prediction of ship-ice collision structure in this paper has reference significance for bow load analysis and structural design of ship navigating in ice covered area.
