为了获得单榫头叶片锻造过程中应力、应变场的分布规律，利用自行开发的三维有限元模拟分析软件对其成形过程进行了模拟分析。研究结果表明：单榫头叶片锻造过程是非稳态的塑性流动过程，叶身横截面内的变形类似于圆柱体的镦粗，且心部所受的变形和三向压应力最大；随着变形程度的增加，等效应力、等效应变等场变量值增加，且变形的不均匀程度也在增加；通过对应力应变的分析可以预测缺陷产生的可能部位，并提出相应的防止措施。该研究对了解和掌握叶片锻造过程的变形规律具有重要意义。
In order to obtain the distribution rule of stress and strain field during forging of single tenon blade, the forming process of the single tenon blade was simulated by using the three-dimensional finite element simulation software developed by ourselves. The results show that the forging process of the single-tenon blade is unsteady plastic flow, the deformation in the cross section of the blade body is similar to the upsetting of the cylinder, and the deformation of the core and the three-direction compressive stress are the most. With the degree of deformation The equivalent field and equivalent strain increase, and the degree of deformation is also increasing. Through the analysis of stress and strain, the possible parts of the defect can be predicted and the corresponding preventive measures are put forward. This study is of great significance to understand and grasp the deformation rules of blade forging process.
