Abstract：

Radial forging experiments of rectangular cross-sectional forging were implemented, and three-dimensional simulation of radial forging process was carried out by finite element (FE) method. However, the deviation between the predicted and measured forging forces under different compression ratio is less than 5%, which shows the reasonableness of the FE model. Then, the influences of radial forging parameters, such as compression ratio and feed ratio, on forging forces and lateral spread were analyzed by the FE simulation. Finally, the relationships of the non-dimensionalized radial forging parameters with forging forces and lateral spread were fitted to quadratic polynomials by the regression orthogonal test method. The deviation between the fitted and simulated results is less than 6%, which shows the rationality of the fitted quadratic polynomials. The fitted quadratic polynomials were used to research on design and optimization of the radial forging process further.
