Применение вариационного принципа минимума полной мощности для анализа процесса прокатки рельсового профиля в универсальном калибре

Abstract

A variation formulation of rail profile rolling in the universal caliber was considered. The geometric model of the deformation zone and a kinematically possible field of metal flow velocities were developed. The boundary conditions on the contact zone were formulated. The system of the basic equations for the minimum total power variation principle was created.
