| 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。

| Abstract: | 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 situation 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 compression 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. |
