摘　　要：为了研究在H型钢轧制过程中轧辊的受力与变形以及变形对轧件轧制的影响,本文以莱钢大型H型钢生产线HN900×300的开坯轧制为例,在有限元软件ABAQUS平台上基于弹性轧辊建立三维热力耦合有限元模型,并考虑了扭矩的单侧输入。根据仿真结果,本文重点分析了轧辊的应力规律和弹性变形。最后将轧辊受到的接触反力与生产规程上的轧制力进行对比,验证了该分析的可行性及有效性,为进一步研究H型钢连轧工艺提供参考。Using the software ABAQUS, a three-dimensional thermo-mechanically coupled FEM model of HN900 × 300 rough rolling process was established, in which, the roller was made as deformable body to research its strength situa- tion and deformation regularity, and the influence to the workpiece from the roller s elastic deformation was taken into consideration too. Based on the simulation results, the principal stress and shear stress of roller as well as its compres- sion deformation and bending deflection were discussed emphatically. Compared the analytical rolling force results to the practical rolling process, this method could provide some valuable references to the rolling practice.
