Abstract：
|
|
The upper bound solution about die forging of straight-axis forged pieces is given in the paper. Based on upper bound theory, the numerical calculation and optimizing process were done by computer, searching for the parameters to be settled, which makes the total energy rate reach the minimun. and deciding the geometrical shape of deformation zone as well as the admissible velocity field of metal flow while forging. Die forging force was calculated, and later, the numerically calculated results were obtained by using the field. The results from theoretical calculation on upper bound theory are closer to those dased on slipline theory.
