Study on Key Factors in Piston Transient Temperature Field

By means of ANSYS, piston finite element model is constructed to attain transient numerical simulation and explore the characteristics of surface temperature. On the basis of experimental design, the correlation is analyzed between major boundary conditions and temperature of feature points, thus revealing the corresponding correlation of quantity. Transient calculation method is proved to be scientific and paves way to defining boundary conditions. And furthermore there forms a theoretical foundation for positioning test point in piston temperature field.
