摘要
The propeller of a polar ship sailing in icy areas will quite likely be subjected to ice loads. Because of the various kinds of ice conditions and propeller working conditions, there are large differences in the types of ice loads acting on a propeller. In this paper, research has been done to investigate the propeller-ice contact and milling loads under different conditions. We established a numerical method for solving this propeller-ice contact problem based on the peridynamics method and the panel method, which numerically simulates the dynamic responses of single ice-blade collisions at different advance speed, contact positions, propeller rotational speeds, and ice sizes. With the help of a Fortran program, we conducted a comparative analysis of the thrust and torque of the blade sustained in six degrees by changing the specified factors, and finally obtained the changing regularity of the milling loads for the blade under different conditions.
