The formula of upsetting deformation force which was deduced according to the plastic processingprinciple theory has been analyzed.Meanwhile, solving the upsetting formation force by adopting the commercial simu -lation software has been studied.By comparing the calculated results and the simulated results , as well as the previousactual measured results, the problem of major quantitative error which was founded in the process of numerical simula -tion of commercial software has been exposed .Therefore, the cause of this problem has been analyzed with improve -ment proposals, as so to lay a certain theoretical and experiential foundation for the future applying of numerical simula -tion software in the field of production for heavy forgings .
