摘要

The considerable amount of ice accumulation on the surface of polar ship superstructure has seriously threatened the navigation safety of the Polar ships. Anti-icing coating has become one of the most effective anti-icing methods for polar ships. When the coating surface is covered with ice for a long time, mechanical de-icing measures should be taken for the icing on the coating surface. In this study, the static icing adhesion shear strength and normal peeling strength of the anti-icing coating were examined, introduction of temperature parameters into existing de-icing criterion, so as to simulate the energy required for mechanical de-icing and the efficiency of de-icing without damaging the anti-icing coating. The simulation analysis of mechanical de-icing and coating peeling of typical hull structures (e.g., flat plate structure, curved parapet structure, curved structure with 70 mm radius and 120 mm radius) was completed in accordance with the criterion. Moreover, the range of energy required for mechanical de-icing and the de-icing efficiency of the above-mentioned typical structures were derived. The de-icing criterion and peeling strength criterion of anti-icing coating and the numerical simulation method proposed in this study can lay a solid technical basis for the design and performance evaluation of polar ship anti-icing systems in the future.
