Abstract
Stern bearings are the main supporting part of ship stern shafts. Water-lubricated stern bearings have the advantages of compact structure, easy maintenance, no waste and no pollution, and. Water-lubricated stern bearing materials are generally non-metallic materials, which are easy to produce elastic deformation when working. Based on this, fiber resin matrix composite materials are selected as water-lubricated stern bearing materials, and the Fluid-Structure interaction numerical method is used to research the lubrication performance of water-lubricated stern bearings, which is verified by the test with water-lubricated stern bearing rig. The effect of rotating speed on the performance of water-lubricated stern bearing under different loads is studied in this paper. The results provide technical and theoretical basis for the study of water-lubricated stern bearings.
