Finite Element Analysis for The Body Frame of Open-Front Press

摘要

Open-front press is one of the dominating equipment for punch forming. Body frame is the primary loadbearing part of this machine, and its rigidity and intensity have great influence on the working performance. In order to optimize the structure of body frame and shorten the product development cycle, finite element analysis, which is an effective technique in CAE, is used to investigate the body frame's deformation and stress distribution in the presented work. By taking JC21-160, a representative type of open-front press, as the analysis object, the whole procedures of this work, such as modeling, meshing, loading, constraint handling and the solving, have been discussed explicitly. The analytical method and result will conduce to improve the structure design of this kind of machine and the similar devices.
