英文摘要：

Taken the research and development of heavy forging process as the object, the characteristics of finite element numerical simulation and physical simulation have been analyzed as well as the relationship between them, and the thought and mechanism of organic integration for simulation technique have been put forward. Furthermore, focused on the problem-solving capability in application, this technique has been applied to the process development of new hot forging technique for heavy shroud ring and also approved by the trial production. This research is very important for currently rapid development of heavy forging production and technique.
