Abstract：

Hydraulic cylinder for hydraulic press is very sensitive to stress as a high pressure vessel. Local high stress always causes damage beforehand. The complex method was adopted as its optimizing arithmetic.The FEM and optimization programme were compiled with FORTRAN language.Quadrangle element was used in automatic mesh. Visualization of preceding and behind disposal were realized on AutoCAD software platform. Having optimized structural parameters, the lower weight cylinder could be got under intensity limit.By selecting optimized flange transitional curve, the stress concentration was reduced. The computation results from this programme were compared to those from theoretical formula to verify the reliability of this software.
