摘要：

为了研究工艺参数的变化对挡圈成形过程中变形扭转的影响，主要基于ABAQUS软件采用有限元动态显示积分算法建立了挡圈三维模型。首先，通过正交试验得到工艺参数对挡圈变形扭转影响的规律为：随着轧辊直径的增大，轧件扭转角先减小、后增大；随着轧辊转速的增大，轧件扭转角先增大、后减小；随着孔型偏转角增大，轧件扭转角减小；影响变形扭转的主次顺序为：孔型偏转角>轧辊转速>轧辊直径；构建了关于轧辊转速、轧辊直径及孔型偏转角的数学回归表达式，通过回归模型分析可知，在扭转角y^最小时，轧辊转速为169 r·min-1、轧辊直径为Φ360 mm、孔型偏转角为13.78°的工艺参数条件对变形扭转的影响最理想。

In order to study the influence of the change of process parameters on the torsion deformation of retainer ring during its forming process, the three-dimensional model of retainer ring based on ABAQUS software was established by the dynamic display integral algorithm of finite element. Then, the influences of process parameters on the torsion deformation of retainer ring were obtained by the orthogonal test. When the roll diameter, the roll speed and the hole deflection angle increase, the torsion angle of rolled piece first decreases and then increases, first increases and then decreases, and decreases respectively, and the primary and secondary sequence influencing the torsion deformation is hole deflection angle>roll speed>roll diameter. Furthermore, a mathematical regression expression for the roll diameter, the roll speed, and the hole deflection angle was constructed. Through the regression model analysis, when the torsion angle y^ was the smallest, the influences of process parameters on the torsion deformation were ideal under the condition of the roll speed was 169 r·min-1, the roll diameter was Φ360 mm, and the hole deflection angle was 13.78°.
