| Abstract: | Stress distribution of the piston in a gasoline engine enlarged is analyzed by applying 3-dimensions CAD/CAE technology. The analyses of coupled-field are performed by coupled-model, such as the temperature field and stress field. Through the analyses, the status of thermal load and combined stress is cleared, and the dangerous stress part is tested. At the same time, the theoretical evidence of piston structure improvement and optimum design has also been presented. |
