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.
During the splitting spinning process, the material parameters of disk blank have a significant effect on the determination of forming parameters and the quality of deformed blank. The influence laws of material parameters, including yield stress, hardening exponent and elastic modulus, on splitting spinning force, splitting spinning moment, degree of inhomogeneous deformation and quality of flange (average thickness and average deviation angle) were investigated by 3D-FE numerical simulation based on elasto-plastic dynamic explicit FEM under ABAQUS/Explicit environment. The results show that, the splitting spinning force and the splitting spinning moment increase with the increase of yield stress, hardening exponent and elastic modulus. The degree of inhomogeneous deformation increases with the decrease of yield stress and hardening exponent and the increase of elastic modulus. The average thickness of flange increases with the decrease of yield stress and the increase of hardening exponent and elastic modulus. The average deviation angle of upper surface increases with the increase of yield stress and the decrease of hardening exponent and elastic modulus. The average deviation angle of lower surface increases with the decrease of yield stress, hardening exponent and elastic modulus. Meanwhile, the corresponding variation ranges are given. The achievements may serve as an important guide for selecting the reasonable processing parameters of splitting spinning based on different aluminum alloys, and are very significant for optimum design and precision control of the splitting spinning process.
以便改进计算精确性和效率，建立合理 3D 是必要的为包括旋转旋转的多传递的女性的模型不仅处理而且弹回并且退火过程。为多传递旋转的一个数字模型用联合被建立明确、含蓄女性，与他们的优点不确和效率。为模型建立的过程详细被介绍，并且模型被验证。到二通行证的旋转的女性的模型显示出的 3D 的应用程序下列:象在完整的旋转进程期间的压力，紧张和墙厚度那样的域变量能被获得，不是仅仅在旋转进程期间而且在期间弹回并且退火进程，并且他们的分布和变化的趋势在对实际多旋转的进程的好同意。因此 3D 为多传递旋转的女性的模型可以是为多传递旋转的过程参数的决心和优化的一个有用工具过程。
