Abstract:Material properties of blank have a great effect on power spinning process of aluminum alloy parts with transverse inner rib. By using finite element(FE) and Taguchi method, the effects and significance of five key material parameters, namely, anisotropic index in thickness direction, yield strength, hardening exponent, strengthening factor and elastic modulus on the formability of inner rib, tendency of wall fracture and degree of inhomogeneous deformation of finished spun parts were obtained. The achievements provide an important guide for selecting reasonable spinning material, and are very significant for the optimum design and precision control of power spinning process of parts with transverse inner rib.
Key words: power spinning; inner rib; Taguchi method; FEM; material properties
