Abstract：

The relationship between structure and stiffness of screw press has always been an important reference in the design of forging equipment. Generally, the mechanical structure obtained by calculating the allowable stress was used, which has sufficient stiffness but bulky equipment. To solve this problem, a parameterized model of EP-10000 was established and its dimensions were changed. The force analysis of the model was carried out by ANSYS, and the stiffness and deformation values of presses with different sizes were obtained under the working condition of 100 MN. Polynomial fitting optimization algorithm was used to establish the mathematical models between the deformation and the length and width of the whole machine and the column width, and under the working condition of 100 MN, the minimum deformation was 0.89873 mm. At this time, the corresponding size of the whole machine was 6700 mm×4126 mm×11385 mm，the column width was 3400 mm, the weight of the whole machine was reduced by about 7.9%, and the strength under this size was 75 MPa, which met the demand. The results show that the high stiffness and lightweight press body can be obtained by this method.
