Abstract：

The power spinning simulation test of 30Cr3 steel was conducted by finite element software ABAQUS, and the process parameters were optimized by introducing Vague set the orthogonal test. Then, taking roller working angle、roller diameter、roller working arc radius, feeding ratio, axial offset, mandrel rotate speed were selected as the optimized process parameters, the orthogonal test of six levels and five factors was designed, and taking the springback amount and the maximum residual stress of spinning part as the evaluation indexes, the optimal combination of process parameters and the influence order of various process parameters on the evaluation indexes were obtained. The results show that the forming quality of spinning part is higher with the roller working angle of 25°, the roller diameter of 185 mm, the roller working arc radius of 9.5 mm, the feeding ratio of 0.5 mm·r-1, the axial offset of 2 mm and the mandrel rotate speed of 60 r·min-1, and the influence order of various process parameters on the forming quality of spinning part is feeding ratio>roller working angle>roller diameter>roll working arc radius>axial offset>mandrel rotate speed. In addition, the simulation results were tested and verified, and the relative error was less than 7%. Thus, it is proved that the simulation results have good reliability and provide theoretical guidance for practical production.
