摘要：

针对复杂异形环件轧制过程中的运动难以控制和质量难以保证的难题，结合复杂异形环件轧制过程的特点，对轧制成形过程材料流动规律进行研究，并结合体积成形过程中的材料变形规律，提出了体积相等、形状相似、截面相等3条复杂异形环件毛坯的优化设计原则，并利用有限元分析方法对所提出的方法的合理性进行了验证。

For the control difficuties of motion and quality during ring rolling, the law of metal flow was studied and a optimal design principle of equal in volume, similar in shape and equal in cross section was put forward combined with volume forming material deformation rule. By the method of FEA, the method rationality is validated.
