| Abstract: | The rear screw propeller profile is very complex. The traditional production technology hasn＇t meet the current demands. In this paper, the author establishes the numerical simulation model for semi-solid forging of the rear screw propeller. Based on the simulation, the possible flaws of the forming process are forecasted and the effects on temperature and load under various punch velocity have been analyzed. It has guidance for optimizing the forming process parameters. |
