摘　　要：以冷轧铅为模型 ,用MARC有限元软件对钢轨的轧制过程进行三维弹塑性模拟 ,并分析轧制状态下钢轨内部应力的分布以及轧后残余应力分布 ,为提高钢轨质量 ,适应国内高速铁路的建设奠定了理论基础。The model of rolling rail in normal temperature was established and rolling process of rail with was simulated by 3-D elastic-plastic FEM, the MARC program was applied to analyze the stress in zone of deform and the residue stress of rail. These will lay a foundation in theory in order to enhance quality of rail so that has been adapted to high speed railway.
