摘　　要：用MARC有限元软件对钢轨的轧制过程进行了三维弹塑性有限元模拟,分析了钢轨的轧后变形、轧制状态下钢轨内部应力的分布以及轧后残余应力分布,为合理配置精轧前万能孔型,指导物理模拟,并为提高钢轨质量奠定了理论基础。The rolling process of rail was simulated by the 3 D elastic-plastic FEM based on the MARC software.The deformation of rail after rolling, the stress in deformation zone and the residue stress of rail has been analyzed.These will lay a foundation in theory in order to arrange the pass in front of finishing mill and enhance quality of rail.
