The Calculation of Deformation Force in Closed Muti-Ram Forging
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.
