The structural static analysis of four-column hydraulic press

The whole three-dimensional model of main cylinder, the column and beam of four-post type hydraulic press which have been established, use the method of finite element, make the simulation for the static performance of the whole structure, obtain the position of stress and strain distribution and stress concentration and the maximum deformation, analyse the strength and stiffness of the structure. The results show that: the structure strength of the hydraulic press is enough but the lack of rigidity of the upper beam and the movable beam, need to improve the design, the results of the analysis provide a theoretical basis for hydraulic structure optimization.
