In addition the material physical parameter variation with temperature was considered in the model. The contact resistance and flash melt were considered in the electric-heat coupling model;
模型中考虑了电、热、力的耦合以及材料物性参数随温度的变化，在电热耦合模型中计入接触电阻与闪光烧损对产热过程的影响；
In the pre-forming die, a resistance wall was adopted to build the flash groove and a convex web structure was used to connect the great varying cross-sections.
在该预锻模中，采用阻力墙形式构造飞边槽，采用凸形连皮结构连接多个大变截面。
