The work aims to solve the problems in high precision, high reliability and stable operation of high-speed and heavy-load die-cutting maneuvering platform with ANSYS finite element software. The finite element analysis software was used to carry out finite element analysis on the existing moving platform to obtain the patterns of stress, strain and displacement of the platform under a certain loading pressure, to determine whether the existing moving platform met the requirements of heavy load, and to obtain the position and space that could be optimized. The finite element analysis of the optimized moving platform was carried out. The results of stress, strain and displacement were compared with those before optimization. The overall weight of the optimized moving platform was reduced by 157 kg, and the maximum deformation of the optimized moving platform was reduced under the same load. The method of finite element analysis can guide the structural optimization design of die-cutting pressure test platform from the theory, improve the accuracy of the design and shorten the trial production cycle of the product.
