In this paper, the BD2 break down rolling process of railway turnout rail in Rail and Beam Plant of Baotou Steel is simulated through finite element modelling (FEM), and the metal flow deformation in rolling process is analyzed as well. The results indicate that the B and C grooves exhibit larger deformation zone in their rail waists, while uniform deformation could be seen in A groove. The equivalent strain of rail waist is larger than that of rail head and base in each pass of BD2.

文章利用有限元模拟了包钢轨梁厂铁路道岔轨BD2开坯轧制过程,分析了轧制过程中的金属流动变形。结果表明,B、C孔轨腰变形量较大,A孔变形均匀。BD2各道次轨腰等效应变大于头底两侧。

文章利用有限元模拟了包钢轨梁厂铁路道岔轨BD2开坯轧制过程,分析了轧制过程中的金属流动变形。结果表明,B、C孔轨腰变形量较大,A孔变形均匀。BD2各道次轨腰等效应变大于头底两侧。

有限元模拟  /  道岔轨  /  应力-应变

In this paper, the BD2 break down rolling process of railway turnout rail in Rail and Beam Plant of Baotou Steel is simulated through finite element modelling (FEM), and the metal flow deformation in rolling process is analyzed as well. The results indicate that the B and C grooves exhibit larger deformation zone in their rail waists, while uniform deformation could be seen in A groove. The equivalent strain of rail waist is larger than that of rail head and base in each pass of BD2.
