Abstract：

For a 30 MN three-beam and four-column double-action tensile hydraulic press initially designed by a company, it is a new hydraulic press. Therefore, the structural analysis and modal analysis on the overall frame of the hydraulic press were carried out by the finite element method to obtain the deformation and stress situations of the main components such as upper beam, slider, base and column. Then, a preliminary check on the hydraulic press was conducted, and its first six natural frequencies were obtained. The results show that the maximum static deflection of upper beam does not meet the engineering requirements, and by optimizing the structure of upper beam, it is close to the engineering requirements. However, the maximum static deflection of slider and base meet the engineering requirements, on the basis of ensuring that the slider and base meet the engineering requirements, the lightweight design of slider and base is further carried out to achieve the purpose of weight reduction, which provides a certain theoretical reference for the design and manufacture of the final 30 MN three-beam and four-column double-action tensile hydraulic press.
