Abstract：

The process of radial forging shaft was numerically simulated by the finite element simulation software FORGE-3D, and the influences of the radial compression value, rotate speed of clamping chuck and axial feeding speed on forging penetration and production efficiency were analyzed. The results show that in the forging process, the smaller the radial compression value is, the higher the rotate speed of clamping chuck is and the slower the axial feed rate is, which results in the smoother forging appearance, smaller rough surface and higher dimensional accuracy. Therefore, the best radial forging process parameters of steel C45 bar with diameter Φ110 mm is determined with the radial compression value of 5 mm, the rotate speed of 30 r·min-1 and the axial feed speed of 20 mm·s-1. The radial forging process is verified and optimized by simulation, which greatly shortens the development cycle and saves costs of multiple forging experiments.
