摘要：

针对圆盘件镦粗成形过程中，接触区不同区域在不同变形程度下的摩擦剪切应力变化复杂的情况，研究了适合于圆盘件锻粗成形的摩擦模型，建立了初始径厚比为5的圆盘件镦粗成形有限元模型，分析了不同摩擦模型在不同变形程度下接触区的分布特点以及制动区半径的变化特点，并与计算结果进行了比较，开展了相关工艺实验验证。结果表明：在圆盘件镦粗成形中，随着变形程度的增加，接触区分布随径厚比的变化而变化，采用修正混合摩擦模型预测的制动区半径变化特点与理论值更接近，其预测精度较高。研究结果为圆盘件塑性成形有限元模拟中摩擦边界条件的设置提供了指导。

During the upsetting process of disc parts, for the complex friction shear stress changes at different areas of contact area under different deformation degrees, the friction model switable for the disc upsetting was studied, the finite element model of upsetting for the disc parts with an initial diameter-thickness ratio of 5 was established, and the distribution characteristics of contact area and the change characteristics of radius in braking area under different deformation degrees for different friction models were analyzed and compared with the calculated results. Then, the relevant process experiments were carried out to verify. The results show that in the upsetting process of disc parts, the distribution of contact area varies with the diameter-thickness ratio as the deformation degree increases, and the change characteristics of radius in braking area predicted by the modified hybrid friction model are closer to the theoretical value, and the prediction accuracy is higher. The results provide guidance for the setting of friction boundary conditions in finite element simulation of plastic forming for disc parts.
