摘要

In this work was performed a comparative analysis of the efficiency of horizontal and vertical rolls in the "rolling-pressing" process. The comparison was performed based on the study of stress-strain state of both variants with the aid of computer simulation in the program DEFORM-3D based on the finite element method. For analysis of the stress state was used the Lode-Nadai coefficient, allowing you to determine which type of deformation is realized at a specific point - tension, compression or shear. For analysis of the strain state was used equivalent strain, which allows to estimate the common level of accumulated strain. In the comparative analysis of parameters of SSS was revealed that the use of vertical rolls at the exit from the matrix during "rolling-pressing" process, allows you to achieve a more favorable distribution of deformation along the entire length of the deformable workpiece.
