立辊轧边的显式动力有限元模拟

Simulation of Edger Rolling by Explicit Dynamic FEM

应用有限元分析软件ANSYS/LS-DYNA对3种不同形状立辊的轧边过程进行了模拟计算,并对轧边后板坯断面形状和平面形状参数进行了分析比较。模拟计算结果表明:用孔型立辊轧边可增加变形渗透程度,轧后板坯具有较好的断面形状和平面形状,使用孔型立辊和锥形立辊均可提高轧制过程的稳定性。

An analog computation was carried out with the FEM software ANSYSrDYNA for the edger rolling processes with three different shapes. The profile parameters of cross-section and plane shape were analyzed and contrasted. From computation results it can be seen that permeation degree of deformation could be increased, and better cross-sectional shape and plane shape were gained when grooved edger was used. The stability of rolling process can be enhanced by using grooved edger or tapered edger.
