| 摘 要： | 镦粗过程中，圆柱坯料易在侧表面形成鼓形。这一问题长期困扰着实际生产。本文主要应用锻造有限元软件DEFORM对几种传统的减小鼓形的措施进行了数值模拟，并将所得到的模拟结果与普通镦粗的模拟结果进行了比较，发现这些措施可以在不同程度上减小了鼓形，并提高了镦粗变形的均匀性。

| Abstract: | In the upsetting proess,it is easy to form drum shape on the side surface of the cylindrical billet, which has puzzled the practical manufacturing for a long time. In this paper, several traditional measures of decreasing drum shape were simulated by the finite element method by using DEFORM software,and their simulated results were compared with the contain upsetting process. We find that the above mentioned measures can decrease drum shape and enhance deformation uniformity in various degrees. |
