Abstract

During the power spinning process of large ellipsoidal heads with variable thicknesses (LEHVT), material parameters of the blank have a significant effect on the quality of LEHVT and the determination of forming parameters. In this paper, the influences of hardening exponent, yield stress and elastic modulus on spinning force, degree of inhomogeneous deformation and unfitability degree are investigated by using 3D-FE numerical simulation under ABAQUS software environment. The results show that, spinning force increases with the increase of hardening exponent, yield stress and elastic modulus. Degree of inhomogeneous deformation increases with the decrease of hardening exponent and the increase of elastic modulus and yield stress. Unfitability degree increases with the decrease of elastic modulus and the increase of hardening exponent and yield stress. The achievements may provide not only an important reference and basis for selecting spinning equipment, but also a guide for quality and process control of the power spinning process of LEHVT.
