Abstract：
|
|
In this paper, the forming process of train wheel was introduced. The upsetting and preforming steps of wheel were simulated. The information of deforming including the material flow pattern, stress in work piece and, forming load were obtained. The influence of the upsetting reduction in height on preform was studied by finite element simulation and the best reduction was concluded. The information provided theoretical base for controlling the process of deforming.
