Abstract: The finite element calculation method of the
piston was investigated with the piston as the research
object. The method of setting the boundary conditions
of the piston temperature field is determined.
Structural analysis software is utilized to conduct a
numerical analysis of the temperature and stress fields
of the piston. The quality loss model examines the
correlation between temperature and piston quality
loss. The research and analysis can provide a more indepth understanding of the heat of the piston and
provide an accurate theoretical basis for optimal
design, such as reducing heat load and improving
stress distribution. It can be used for failure analysis of
aircraft engine pistons, etc. to enhance the reliability
and longevity of aviation piston engines.

Keywords: piston, thermo-mechanical coupling, quality loss, temperature field.
