摘　　要：为探究对数螺旋线应用于轧制领域可行性,本文提出一种对数螺旋线轧辊辊型,并拟合出对数螺旋线辊型曲线方程,应用ABAQUS软件对该辊型轧辊和传统余弦曲线辊型轧辊的轧制过程进行三维动态仿真,对比分析带钢浪形和凸度值。结果表明,对数螺旋线辊型轧辊对带钢浪型和板凸度的控制均优于传统余弦曲线辊型轧辊。In order to explore the feasibility of applying logarithmic spiral in the field of rolling,a new logarithmic spiral roll profile was proposed,and its equation was obtained by fitting. ABAQUS software was used to simulate the three-dimensional rolling processes of the new roll profile and the traditional cosine roll profile,and the wave shape and the convexity of the strips were comparatively analyzed. The results show that the new roll profile is more prominent in controlling wave shape and convexity than the traditional cosine roll profile.
