摘要
本文建立了用有限元进行变形一传热耦合分析的计算模型,提出了既能保证足够的计算精度,又可以在微机上实施的耦合方法,对热态镦粗过程进行了热力耦合分析计算,计算结果与实施结果相当符合。
In this thesis, a calculating model of thermo—mechanical coupled finite element analysis is es tablished, presenting a coupled method of sufficient precision and for using a microcomputer. A ho(?)upset process is analyzed using this method. Calculations are found tO be in complete accord with evperimental results.
