Abstract

A three-dimensional elastic-plastic FE(finite element) model of power spinning of thin-walled Ti2AlNb alloy shell was established based on the dynamic, explicit module of FE software. The key technologies, including contact boundary, mesh, were dealt with reasonably. The reliability of model was validated by theoretical evaluation. To find a optimal combination of processing parameters, an L9(34) orthogonal test was adopted. The results showed that the feed velocity of roller had the most significant influence on the fracture trend, and the mandrel velocity on the wrinkle trend. The optimal processing parameters combination was v2n1r3t3. Based on this model, the distribution of strain of both sides of workpiece was obtained in order to research the reason of the fracture and wrinkle of workpiece. The strain of outer side was larger than that of inner side. The results conformed to the practical power spinning process.
