Abstract：

To investigate the deformation characteristics of spun parts with noncircular cross-section, the simulation of spinning process of conical parts with pentagonal cross-section was carried out with software MSC.Marc. The distributions of thickness thinning ratio along the circumference and generatrix directions were obtained. The influence of cross-section shape of workpiece on thickness thinning ratio was obtained by comparing the thickness thinning ratio of several spun parts with pentagonal and circular cross-sections. The results show that the distribution of thickness thinning ratio along the circumferential direction is related to the contour curvature closely, the bigger of the curvature, the larger of the thickness reduction, and vice-versa.
