| Abstract: | The finite volume method (FVM), which is free of rezoning, is applied in the simulation of the metal forging process. In particular, this paper first introduces the governing equations of FVM for metal forging and then discusses the key techniques such as dynamic boundary tracing and the application of friction boundary. In addition, the forging process of one connecting rod is simulated with FVM, with the metal flow process, the distributions of effective strain and temperature during the forging process carefully analyzed. The results indicate that FVM is an especially useful numerical simulation method for the whole multi-stage forging processes. |
