| 中文摘要: |
| 通过对锻件结构的分析,设计了辊锻制坯+终锻的生产工艺。 运用有限元分析技术,通过对比分析,重点研究了新过程终锻成形时金属流动情况、等效应力应变分布,并对锻件的晶粒度进行了预测。 通过对锻件成形、载荷及质量等的综合评定表明,新的生产工艺在改善锻件质量、提高材料利用率与模具寿命等方面具有明显优势。 |
| 英文摘要: |
| Roll forging billet and then finish forging were designed as a new process of production based on the analysis of the structure of forgings. The finite element analysis techniques were used to research on the metal flow, stress and strain distribution and grain size prediction in the new process. The results show that the new process of production has obvious advantages in improving the quality of forgings, material utilization and die life through comprehensive assessment of forming, load and quality. |
