Mechanics Performance of the Stern Bearing Surface Damage by Finite Element Analysis

Ship stern bearing can be damaged in the process of operation, the study about mechanical properties of the surface damage of the stern bearing has great help to improve its service life. The statics analysis of three different indentation form and different diameter three indentation has been studied by finite element method (fem), such as circular arc form, rectangle and triangle. Results show that the triangle pit damage forms of bearing is the most damage, should try to avoid its appear; The size of the diameter of three pits also can produce great influence on statics performance.
