The aim of this study was to solve the difficulty in spinning forming of a certain type of tension wheel with transverse inner ribs. The finite element model for tension wheel was built based on the finite element simulation software. The spinning forming process of the tension wheel was numerically simulated by selecting different parameters of tube thickness and spinning roller arc radius. The effects of the wall thickness of tube and spinning roller arc radius during the spinning forming process on the spinning force and forming quality were obtained, and the results were summarized. Through analysis of the effects of wall thickness and the pre-forming roller shape on the spinning forming quality of the tension wheel, the optimal process parameters were obtained, which provide guidance for the actual production of the part.
