Abstract

Радиально-аксиальная раскатка колец представляет собой метод ступенчатого деформирования, применяемый при изготовлении бесшовных колец. Преимущества данного метода заключаются в высокой точности изготовления, кратковременном производственном цикле, а также значительной экономии материала. При этом отмечается неравномерность температуры и колебания пластической деформации. Технологические параметры, такие как скорость подачи раскатки, скорость вращения главного валка и скорость осевой подачи валка, оказывают влияние на распределение температуры и деформаций. Для изучения воздействия различных комбинаций технологических параметров на равномерность температуры и деформаций с помощью комплекса ABAQUS/Explicit проводится сопряженный термомеханический КЭ-анализ. Для определения оптимальных технологических параметров применяется метод Тагути. Для оценки влияния технологических параметров на пластическую деформацию и температуру проводят анализ ANOVA, или дисперсионный анализ.
