The finite element analysis software is used to analyze the full simulation simulation of large multi-directional servo hydraulic press multi-cylinder with step-by-step pressing of various working conditions,establish a full simulation model of large-scale servo press fuselage,and conduct full simulation analysis of vertical fuselage and horizontal fuselage under various working conditions of preload and multi-cylinder step-by-step suppression,so as to ensure that the strength and stiffness of the multi-directional servo hydraulic press meet the design and meet the actual working conditions.The results show that the vertical and horizontal fuselage of the multi-directional servo hydraulic press are under full load conditions,the multi-cylinder with stepby-step pressing fuselage stress is less than the permissible stress,and the stiffness meets the requirements of the use condition,and the research methods and results provide guidance for the design of the vertical and horizontal fuselage under multiple working conditions of the multi-cylinder step-by-step suppression of large servo hydraulic presses.
