Abstract：

For the problems of slit and deformation for the pretightened combination frame of 100 MN hydraulic forging machine during loading, three dimension model of frame was built by SolidWorks, and the static analysis on the frame of hydraulic forging machine was conducted by ANSYS Workbench. Then, the relationships between pretightening coefficient and slit as well as deformation coefficient of frame were obtained, and the optimum pretightening force was determined to be 160 MN. Furthermore, the positions of the maximum deformation and stress concentration in the frame were analyzed by the deformation and stress nephograms of the frame during loading, the thickness and fillet radius of Cshaped plate as well as the structure of upper partition beam were optimized on this basis, and the static analysis of the optimized frame structure was analyzed again. The results show that the maximum stress is 166.56 MPa after optimization of the frame structure, which satisfies the original design strength requirement. In addition, the deformation coefficient of frame reduces, and the deformation in the vertical direction reduces significantly.
