Abstract

Aiming at the problem of heat load in high-silicon aluminum cylinder for high detonation pressure diesel

the mathematical models and boundary conditions between temperature and stress were established.The characteristic of heat load in the high-silicon aluminum cylinder at a given condition was described by calculating temperature field

thermal stress and strain fields through Ansys.The results reveal that in high-silicon aluminum cylinder

the overall temperature field is descended from top to bottom axially

and the maximum temperature occurs at the upper of inner wall of the cylinder.The thermal deformation is characterized by large deforming at upper with small deforming at lower.
