Численное определение усилий при двухпроходной формовке заготовки подшипникового кольца

Abstract

Numerical simulation of bearing ring hot forging manufacturing operations: upsetting and forming was done in the research. Coupled boundary non-stationary contact thermoviscoplastic problem was solved. Its numerical implementation was done by finite element method with application of customized software package. Stress-strain analysis defined dependence of forces at forging from time for upsetting, single- or two-pass forming. Data analysis showed that single-pass forming expends 12 % of power more than during two-pass forming.
