| Abstract: | Based on ANSYS 10.0 Workbench Environment and using third thermal boundary conditions and method of indirect thermal-structural couplings,analysis of the thermal stress field of the piston for 150 diesel engine was made. On the basis of analysis,the structure of piston pin hole has been improved,and the dimension has been optimized using the method of DOE. After the optimization,the stress of the piston pin hole decreased by 22.6%. |
