Flat container is an important structural part for extruding flat and wide profiles,and its maxi-mum stress generally occurs on the inner wall. Because the inner hole is not round,the stress distribution is very uneven,and there is a serious stress concentration. The stress concentration of the inner wall is closely related to the shape of the inner hole,and also affects the stress state of the whole structure of the flat container. The thermal and structural coupling analysis of the flat container structure was carried out by using the finite element method to simulate the deformation and stress state of the container loaded under various working conditions. The strength simulation calculation of the flat container structure with three kinds of inner holes was carried out respectively,and the deformation,stress state and process feasibility of the container structure with different inner hole shapes were compared,which provided references for manufac-turing and optimization design.
