Abstract: Hollow parts always work in an uneven steady-state temperature field.Causes of hollow part's thermal deformation include thermal stress and thermal expansion.An equation based on thermoelasticity method with a hollow part in an uneven steady-state temperature field is derived.The equation is verified by experimental results.

Key words: uneven steady-state temperature field, hollow part, thermal deformation
