In the paper, by rigid-plasticity finite element software Deform-3D, the hot forging process of the crankshaft is analyzed under different technologic conditions. The results indicate that the pivotal data obtained by the finite element simulation has a good agreement with the practical productions and can be supplied to the practical production. The time of die trial and the costs of production can be reduced to a great extent and the production efficiency can be improved.
