Features Finite-Element Modeling of the Deformation Exact Mass

Abstract

The characteristics of finite-element modeling of deformation of billets of railway wheels are considered. On the basis of the performed theoretical and experimental researches, the influence of the basic parameters of the finite-element models on the accuracy of the calculation of the metal forming and forces in the rolling and stamping wheels billet was established. The research included an analysis of power and speed parameters of stamping and rolling wheels billet on the basis of experimental data. Also work on the finite-element modeling of processes stamping between smooth plates, stamping by punch, forming at rolling dies and wheels billet rolling were carried out. It is shown that when creating the models making simplification of the problem can lead to significant distortions of the calculation results, making them unsuitable for practical use.
