The calculation of deformation force in closed multi-ram forging

摘要

With the example of rod, this paper introduces principal stress method in the analysis and calculation of deformation force in complex parts manufactured by closed multi-ram forging. The relationship between deformation force and stroke is simulated by rigid-plastic finite element software, and then verified by experiment.It has been shown that principal stress method are accurate in calculating the deformation force of multi-ram forging by comparing and analyzing the results of these three ways.
