The article presents a method of numerical modeling of the process of sheet metal stamping in
rigid matrices for
aircraft axisymmetric parts. We applied ANSYS environment (modules
Transient Structural and Autodyn) for non-stationary and dynamic tasks. The aim of the
study is to
reduce the time for experimental testing of the technological process. We show the
results of mathematical modeling of a workpiece stamping process using a ductile metal
considering
different values of the strain rates and the coefficient of friction between the
matrix and the workpiece
. We found out that when forming parts with a small deflection
(less than 0.2) from different materials the speed of the punch and the sliding friction force
did not have a significant effect on the thickness and final shape of the resulting part. How-
ever, as the transfer speed of the punch increases, its significance increases for the parts
with a high deflection.
Keywords:
numerical modeling, stamping, punch, deformation of the workpiece material,
