Abstract: This article is about the research to vertical post' s pre - tightening for 600 - ton full automatic tile with the method of contract finite element analysis. Traditional press finite element analysis is a method that cross beam, vertical post' s and base as lonely parts and regards each part as a whole which is linked fimly and ignores the contract parts' non - line properties . The article also has a contract between traditional finite element analysis and contract finite element. In calculating result, comparison analysis shows that three is obvious difference between the two methods. Considering the press fnite element analysis which includes contract properties is more approach to actual working condi- tions . So that analysis methods also applies to other press with vertical post.

Key words: press, contract finite element
