STRESS ANALYSIS OF MULTILAYER FLAT CONTAINER FOR EXTRUDING ALUMINUM SHEET WITH FLANGE BY FEM

摘要

The stress distribution and strength condition of multilayer flat container for extruding aluminum sheets with flange have been simulated by elastic FEM under different extrusion pressure, hole sizes and shrink-fitting ranges. The results show that the distribution of shrink-fitting pressure is not uniform on the shrink-fitting interface, the maximum allowed extrusion pressure is 500MPa with present container of hole size 850×250mm and 600MPa with the hole size being changed into 850×320mm.
