摘要：
This paper simplifies the complex propeller geometry into hydrofoil sections to analyze the interaction mechanism between propeller and sea ice during polar navigation. A numerical analysis method for two-dimensional rigid hydrofoil ice-cutting is proposed based on the peridynamics theory and the elastic-brittle constitutive model. The reliability of the method in predicting ice-cutting loads is validated, and the evolution law of ice crushing during the hydrofoil ice-cutting process is analyzed. The influence of parameters such as cutting thickness, hydrofoil section shape, and cutting angle of attack on ice crushing characteristics and ice loads is systematically investigated. The study provides an important reference for revealing the load characteristics of ice-class propellers and optimizing blade design.
