摘　　要：目的　用有限元法探索斜轧变形的规律 .方法　在分析和合理简化的基础上 ,提出斜轧变形的有限元法模型 ,以 ANSYS软件为工具 ,对该模型进行计算分析 .结果　获得轧件横断面内的应力和应变分布 .结论　结果与其他方法的结果相吻合 ,曼内斯曼 (Manesmann)Aim: To study deformation of skew rolling with helical groove. Methods: After FEM model of skew rolling with helical groove is established by reasonable analysis and simplification of the metal forming process, numerical simulation is done for the model by means of ANSYS software. Results: Stress and strain distribution in the cross-section of workpiece are found. Conclusion: The result of simulation is confirmed with that obtained by other methods. Mannesmann effect is caused by fatigue of the central part of workpiece.
