As for the phenomenon of the bottom thermal inward convex distortion of the Composite Bottom Pan (CBP) on the condition of heating, the mechanism of the bottom distortion was researched on the basis of ANSYS 10.0 considering the structural characteristic and the heating conditions of the composite bottom pan. The results showed that the thicker the bottom of the composite bottom pan, the smaller its thermal deformation amount. The thicker the junction of the pot and wall was, the smaller its deformation. And it was helpful for reduction of deformation to use a big rounded transition. The increase of rings number of magnetic conductive sheet would lead to a less bottom thermal inward convex distortion of the CBP. The larger the area of the additional stainless steel sheet (or ring), the smaller the deformation amount. Consequently, the research laid a solid theoretical foundation for the design and optimization of the structure of composite bottom pan.
