| Abstract: | A numerical simulation of large gear forging process with to sub-procedures by elastoplastic finite element method is presented. First a steel cylinder is formed into a middle blank, then the middle blank is formed into a large gear blank. The strain field and stress field as well as full degree are gained by this FEM simulation. The result shows that both shape and size of the middle blank and last blank are consistent with experimental cases. This result has important guide to both the selection of forging parameters and the design of die. |
