| Abstract: | Based on the finite element method,the load optimization model of the stern tube bearing was set up.The choice principles and influence factors of the objective function,constraints and design variable in the course of the load optimization were discussed about.Load optimization results by the APDL program showed that the stern tube bearing load can be lowered about 11%,which can reduce wear of the stern tube bearing and increase bearing′s life. |
