In order to improve the working condition of low speed, the stern bearing friction caused by poor lubrication of abnormal vibration and noise problem, this paper starts from the influence of problem, takes the circular, elliptical, square, I-shaped and triangular cavity as the research object, establishes the water lubricated stern bearing model, and carries on the mechanical analysis of the model by using ANSYS/Workbench; and on this basis, study the effect of the diameter of the cavity on the mechanical properties of stern bearing. The results show that the displacement, strain and stress of circular cavity bearing are better than other geometric cavity bearings. Among them, the mechanical properties of 3∼4mm have a better performance.
