中文摘要：对导向辊的运动轨迹进行了分析，得出其运动坐标随时间变化的解析表达式，编写了MATLAB计算程序对表达式进行求解。基于ABAQUS对冷辗扩过程进行了数值模拟，并在D50G91轧环机上轧制出了质量较好的环件成品。
英文摘要：The analytic equation of guide roller movement coordinates changing with time was deduced by sufficient analysis for trajectory. MATLAB program was used to calculate the equation. The ring rolling simulation was analyzed based on ABAQUS. And then the qualified products were produced by D50G91 roller.
