Abstract：

The orthogonal experiment method was introduced to analyze the effects of various process parameters and the interaction among them on forging load and load on mandrel in radial forging process of barrel, and to obtain the optimum process parameters. The axisymmetric FE model was used to simulate the radial forging process of barrel under different process parameter values, and its accuracy was verified by comparison forging loads predicted by FE model with the experimental results. An analysis of variance was performed to establish the relative significance of various process parameters and to obtain the optimum process parameters, the optimum results were predicted under the optimum process parameters, and the FE model results were used to verify the predicted results.
