螺旋桨-冰切削过程中接触载荷试验
Test of contact loads during propeller-ice milling process
摘要
Abstract
The collision of ice on a propeller is a very complicated occurrence , which often leads to deformation and damage of propeller blades , and affects the navigation and safety of a ship.To study propeller-ice milling and colli-sion, in this paper, milling tests of propeller-ice were separately carried out in air and water with different pushing speeds, milling depth of model ice , revolution speeds, and advance coefficients of propeller.The thrust and torque of the propeller were measured.The results show that in the process of propeller-ice milling in air, the deeper the milling depth, the smaller the thrust , and the greater the torque.Furthermore, when the pushing speed of the mod-el ice was faster , the thrust and torque of the propeller were greater.During propeller-ice milling in water, the dee-per the milling depth, the greater the thrust and torque of the propeller.With a change in the pushing speed of the model ice, the increment of the thrust and torque of the propeller is not obvious , and they do not constantly in-crease when the distance between the propeller and ice reduces.关键词
