摘　　要：基于阶梯形环件轧制理论,初步设计模具、毛坯和工艺参数,应用Abaqus软件建立轧制的三维模型,并利用Abaqus/Exp lic it显式算法对阶梯形环件轴承外圈的冷辗扩成形进行模拟分析,揭示出梯形环件轧制缺陷的成形机理和轧制过程中金属流动的特性。并在KRD160精密辗环机上进行轧制试验,验证了毛坯和模具的形状合理。Based on the theory of step ring rolling, the mould, the ring blank and the technique parameters are pre - designed. Abaqus is used to build 3 - dimention rolling model, and the Abaqus/Explicit finite element method is used to analyze the cold roiling of step outer ring, mechanism of rolling deformation defects of step outer, the metal flow characteristic during rolling process. The cold ring rolling experience is made in KRD160, the result indicate that ring blank and mould are reasonable.
