| 回顾了环件径-轴双向轧制锻透条件、咬入条件、刚度条件等相关理论研究进展，分析了工艺参数对轧制过程的影响及其确定准则，在此基础上引入轧制曲线的概念，并给出了径-轴双向环轧轧制曲线的设计原则，还探讨了在利用有限元方法模拟轧制过程、优化轧制工艺参数时存在的问题，并给出了对数值模型进行控制和处理的有效方法。 |
| 英文摘要: |
| The recent theoretic research progress of Radial-axial ring rolling, such as condition of roll deformation across the section of ring, condition of roll bite and condition of ring rigidity, were reviewed in this paper. The effect which caused by process parameters and the design principles of process parameters were analysed. On that basis the concept of rolling curve was introduced, and the design principles of rolling curve of Radial-axial ring rolling was given. The problems which appeared in the process of using finite element method for simulating rolling process and optimizing ring rolling process parameters were discussed, and the effective method for controlling and handling numerical model was given, the researches provided references for choice of rolling process parameters and boundary condition of ring and roll in finite element simulation. |
