Abstract
It usually causes the crushed ice to sink on the bow when ships sail in the ice zone. The crushed ice is gradually sliding to the flow field in front of propeller along the hull, resulting in high-speed rotation of the propeller and ice milling, so that the propeller receives severe deformation and damage. In order to further analyze and study various loads in propeller-ice milling process, the testing apparatus of propellerice milling was setup in towing tank, and the measurement equipment and model ice feeding mechanism are described in detail. And, the feasibility and reliability of the testing apparatus are validated by the repeatability analysis and the comparison with the results of other scholars. Finally, the loads of the propeller-ice milling in air as well as in water were analyzed in detail. The experimental results show that the construction of the testing apparatus of propeller-ice milling is feasible and can do a better measure of milling loads of propeller-ice. The faster the model ice moves, the greater the compressive load on the propeller. Detailed description of contact load during propeller-ice milling has an important engineering significance and applications value for the structure design of the ice propeller.
