Parameters and Path Optimization on Formidability of Incremental Sheet Forming

Abstract:

On the basis of ANSYS/LS-DYNA, the finite element model of incremented forming of conical part was constructed. The plastic deformation area of blank was increased and crack was delayed in multistage. Forming parts with the angle of 90°use multistage forming. Focused on the investigation of the influence of process parameters on the thinning rate and the thickness distribution then least-square response surface method was adopted to set up the approximate optimization model for thinning. The optimization on the approximate model was carried out using sequential quadratic programming method. The results show that the experimentally thinning rate is consistent with the theoretic result based on the homogeneous thickness distribution.
