摘　　要：火车车轮镦粗工艺对火车车轮成形后续工艺影响很大。在对车轮镦粗工步进行理论分析的基础上采用有限元软件DEFORM对镦粗及预成形工步进行了有限元模拟。研究了镦粗工艺对后续预成形工步的影响,为车轮成形工艺设计提供了理论依据。The upsetting process of train wheel has a great influence on the follow-up process of train wheel forming. Finite element simulation for upsetting and performing steps has been done by finite software DEFORM on the basis of theoretical analysis for upsetting steps of wheel. The influence of upsetting process to the follow-up performing steps has been studied, which provides theoretical basis for the process of forming.
