| 摘 要： | 以汽车丁字臂零件为对象，分析了原有锻造工艺过程，根据金属塑性流动理论和设计方法，改进了丁字臂零件锻造成形工艺。采用有限元数值模拟软件对其改进后制坯工艺过程、金属填充状态进行模拟分析，同时对比分析了改进前后终锻等效应变分布和成形载荷。结果表明改进后的工艺提高了零件的材料利用率和模具寿命。模拟结果与实验结果吻合，对实际生产起到了指导作用。

| Abstract: | In this paper, the original forging process of automobile T-shaped part is analyzed. According to the metallic plastic flow theory and design methods, the forging forming process of the T-shaped parts is improved. There were simulated and analyzed that the process of blank making,the filled state of metal. Besides, Effective strain fields and the load of before and after Improving of T-shaped part were compared. It is indicated that improved process can improve material utilization ratio and die life. The simulation is in agreement with experimental results. It has provided a theoretical basis to guide the practical production. |
