| 摘要: |
| 为了有效控制壁厚渐变锥形旋压件的变形，实现该类钣金机匣零件的精确成形，通过实验方法建立了GH3030高温合金常温下真应力-真应变曲线方程。在此基础上，建立了GH3030高温合金壁厚渐变锥形回转件强力旋压有限元模型，采用有限元模拟和实验相结合的研究方法，对其强力旋压成形进行仿真，详细分析成形中的等效应力场、应变场的分布特征，获得其分布规律，阐明了GH3030高温合金壁厚渐变锥形回转件强力旋压成形机理；并通过锥筒凸缘平面度实验测试对仿真结果进行了验证。研究结果为控制壁厚渐变锥形回转件成形质量提供理论依据。 |

| Abstract: |
| In order to effectively control the deformation of tapered spinning parts with gradually changing wall thickness, the precise forming of such sheet metal casing parts can be realized. This paper uses experiments to establish the true stress-strain curve equations of GH3030 superalloy at normal temperature. Based on the equations, it establishes the finite element model of the strong spinning forming of a GH3030 superalloy tapered rotary part with wall thickness gradient. The equivalent stress field for the strong spinning forming is used to combine the finite element simulation with experiments. The strong spinning forming is simulated, and the distribution characteristics of the equivalent stress field and the equivalent strain field for the strong spinning forming are analyzed in some detail, and their distribution law is obtained. The strong spinning forming mechanisms for the GH3030 superalloy tapered rotary part with wall thickness gradient is clarified. The experimental and simulation results are verified with the conical flange plane degree. |
